The first support portion can be connected to both the upper shaft gear assembly 200 and the lower shaft gear assembly 300, so that the first support portion can adjust the upper shaft gear assembly 200 and the lower shaft gear assembly 300 in the up-down direction by lifting and lowering the first support member 21; the first support portion can also be connected only to the upper shaft gear assembly 200, so that the first support portion can adjust the upper shaft gear assembly 200 in the up-down direction by lifting and lowering the first support member 21; the first support portion can also be connected only to the lower shaft gear assembly 300, so that the first support portion can adjust the upper shaft gear assembly 300 in the up-down direction by lifting and lowering the first support member 21.

[0047] Reference Figure 2 As shown, the adjustment mechanism is located on the upper side of the base 10, and the adjustment mechanism includes a first driving member 31, and the first driving member 31 is connected to the first transmission member 22, so that the first driving member 31 can drive the first transmission member 22 to move, so that the first transmission member 22 can drive the first support rod 211 to move in the up and down directions. The first support portion located on the first support member 21 is connected to the upper shaft gear assembly 200 and the lower shaft gear assembly 300, or is only connected to one of the upper shaft gear assembly 200 and the lower shaft gear assembly 300, so that one or both of the upper shaft gear assembly 200 and the lower shaft gear assembly 300 can be moved in the up and down directions.

[0048] The following describes the assembly process of the transmission assembly tool 100 according to the embodiment of the present invention for assembling the upper shaft gear assembly 200 and the lower shaft gear assembly 300 of the transmission.

[0049] The transmission assembly tool 100 of this embodiment includes two first lifting mechanisms 20 , wherein one of the first lifting mechanisms 20 supports the upper shaft gear assembly 200 through a first supporting portion, and the other first lifting mechanism 20 supports the lower shaft gear assembly 300 through a first supporting portion.

[0050] The transmission assembly tool 100 is placed on the workbench, the first driving member 31 is driven, the two first supporting members 21 are adjusted to a suitable height, the housing 500 of the transmission is placed on the transmission assembly tool 100, and the first supporting member 21 passes through the corresponding hole position on the housing 500. The differential assembly is placed on the housing 500, and the upper shaft gear assembly 200 and the lower shaft gear assembly 300 are placed on the two first supporting members 21 respectively, and the upper shaft gear assembly 200 and the lower shaft gear assembly 300 are pre-assembled; the first driving member 31 is driven, and the first driving member 31 drives the first transmission member 22, so that the first supporting member 21 descends, thereby driving the upper shaft gear assembly 200 and the lower shaft gear assembly 300 to descend, until the upper shaft gear assembly 200 and the lower shaft gear assembly 300 contact the bottom of the transmission housing 500, at which time, the upper shaft gear assembly 200 and the lower shaft gear assembly 300 stop descending, thereby completing the assembly.

[0051] According to the transmission assembly tool 100 of the embodiment of the utility model, by setting at least one first lifting mechanism 20, and adopting a first support part located on the first support member 21 to be connected to at least one of the upper shaft gear assembly 200 and the lower shaft gear assembly 300, and adopting a first driving member 31 to drive the first lifting mechanism 20 to move, at least one transmission shaft assembly can be moved upward or downward synchronously. Compared with the traditional assembly method that requires multiple people to cooperate in installing the upper shaft gear assembly 200 and the lower shaft gear assembly 300, the use of the transmission assembly tool 100 for assembly can reduce the difficulty of assembling the transmission. At the same time, since only one person is required to operate the transmission assembly tool 100, the assembly efficiency can be improved and the risk of gear damage to the transmission during the assembly process can be reduced.

[0052] Optionally, a plurality of fourth weight-reducing holes 14 and a plurality of base fixing holes 15 are formed on the base 10. The base fixing holes 15 are used to fix the transmission assembly tool 100 to the workbench by passing screws or bolts through the base fixing holes 15 when using the transmission assembly tool 100.

[0053] According to some embodiments of the utility model, the first transmission member 22 includes a first rod 222 and a first gear 221, the first driving member 31 is a driving gear, the driving gear is engaged with the first gear 221 to drive the first gear 221 to rotate, the first rod 222 is coaxially fixed with the first gear 221, and the first rod 222 is threadedly engaged with the first support member 21.

[0054] Reference Figure 2 and Figure 4As shown, the first transmission member 22 includes a first rod 222 and a first gear 221. The first rod 222 is coaxially fixed with the first gear 221, so that the first rod 222 can obtain the same rotation speed as the first gear. The first driving member 31 is a driving gear, and the first driving member 31 is meshed with the first gear 221, so that the first driving member 31 can drive the first gear 221 to rotate, thereby making the first rod 222 and the first gear 221 rotate at the same speed. Since the first rod 222 is threadedly meshed with the first support member 21, the first rod 222 and the first support member 21 can move relative to each other in the up and down directions.

[0055] The first driving member 31 is meshed with the first gear 221. The rotation of the first driving member 31 drives the first gear 221 to rotate. At the same time, the first rod 222 rotates, so that the support member can move in the up and down directions, driving at least one of the upper shaft gear assembly 200 and the lower shaft gear assembly 300 to move in the up and down directions.

[0056] By adopting gear transmission between the first driving member 31 and the first gear 221, the transmission accuracy and efficiency of the first driving member 31 and the first gear 221 can be high, the transmission process of the first driving member 31 and the first gear 221 can be stable, and the compact structure of the first driving member 31 and the first gear 221 can also make the maintenance of the first driving member 31 and the first gear 221 simple, thereby better controlling at least one of the upper shaft gear assembly 200 and the lower shaft gear assembly 300 to move in the up and down directions.

[0057] By setting the first support member 21 to be threadedly engaged with the first rod 222, the rotational movement of the first rod 222 can be transmitted to the first support member 21, so that the first support member 21 moves in a straight line. The threaded engagement structure of the first support member 21 and the first rod 222 is simple, which is convenient for the processing and production of the first support member 21 and the first rod 222. The threaded transmission between the first support member 21 and the first rod 222 has high precision and high stability.

[0058] Furthermore, the first driving member 31 includes: a rotating shaft and a driving tooth portion coaxially fixed to the rotating shaft. A third threaded hole 13 and a fixing column fixed in the third threaded hole 13 are formed on the base 10. The rotating shaft is sleeved on the fixing column and is rotatably connected to the fixing column.

[0059] Optionally, a plurality of first weight-reducing holes 2211 are formed on the first gear 221 , and a plurality of third weight-reducing holes 311 are formed on the driving tooth portion of the first driving member 31 .

[0060] According to some embodiments of the utility model, the first rod 222 is a hollow column, an internal thread is formed on the inner circumferential wall of the first rod 222, the first support member 21 is a rod-shaped extending up and down, an external thread that is adapted to the internal thread of the first rod 222 is formed on the outer circumferential surface of the first support member 21, the first rod 222 is sleeved on the radial outer side of the first support member 21 and is connected to the first support member 21 through the internal thread to drive the first support member 21 to move up and down.

[0061] Reference Figure 2 and Figure 4 As shown, the first rod 222 is a hollow column extending in the up-down direction, with an internal thread formed on the inner peripheral wall, and the first support member 21 is a rod extending up-down, with an external thread formed on the outer peripheral surface. The first rod 222 is located outside the first support member 21, so that the first rod 222 and the first support can rotate relative to each other, and through threaded engagement, the first rod 222 and the first support member 21 can move relative to each other in the up-down direction.

[0062] The first driving member 31 is meshed with the first gear 221. The rotation of the first driving member 31 drives the first gear 221 to rotate. At the same time, the first rod 222 rotates. The internal thread of the inner circumferential wall of the first rod 222 is meshed with the external thread of the first support member 21, so that the first support member 21 can move in the up and down directions, driving at least one of the upper shaft gear assembly 200 and the lower shaft gear assembly 300 to move in the up and down directions, so as to assemble the upper shaft gear assembly 200 and the lower shaft gear assembly 300 to a predetermined position.

[0063] By setting the first rod 222 to be a hollow column and the first support member 21 to be a rod extending up and down, the first support member 21 can be moved in a straight line direction. At the same time, the first rod 222 provides a containing space for the first support member 21 and has a guiding function.

[0064] By setting the internal thread of the inner circumferential wall of the first rod 222 to mesh with the external thread of the first support member 21, the rotational motion of the first rod 222 can be transmitted to the first support member 21, so that the first support member 21 moves in a straight line. The threaded meshing structure of the first support member 21 and the first rod 222 is simple, which is convenient for the processing and production of the first support member 21 and the first rod 222. The threaded transmission between the first support member 21 and the first rod 222 has high precision and high stability.

[0065] According to some embodiments of the utility model, the first lifting mechanism 20 also includes: a first guide rod 23, the first guide rod 23 extends vertically, the lower end of the first guide rod 23 is fixed to the base 10, the first support member 21 is hollow rod-shaped and defines a first guide hole 213 on the inner side, the first support rod 211 is sleeved on the first guide rod 23 through the first guide hole 213, wherein the cross-section of the first guide rod 23 is non-circular, and the cross-section of the first guide hole 213 is adapted to the cross-sectional shape of the first guide rod 23.

[0066] Reference Figure 2-Figure 7 - Figure 8 As shown, the first support member 21 is located outside the first guide rod 23, and the first support rod 211 is sleeved on the first guide rod 23 through the first guide hole 213. The first guide rod 23 and the first support member 21 both extend vertically, so that the first guide rod 23 and the first support member 21 can move in the up and down directions.

[0067] The lower end of the first guide rod 23 is fixed to the base 10. For example, the base 10 is formed with a first threaded hole 11, and the lower end of the first guide rod 23 extends into the first threaded hole 11 and is threadedly connected to the base 10. In this way, the first guide rod 23 can be prevented from moving relative to the base 10 and the first transmission member 22 can rotate around the first guide rod 23. The cross section of the first guide rod 23 is non-circular, such as elliptical, semicircular, rectangular, triangular, pentagonal, trapezoidal and hexagonal. The cross section of the first guide hole 213 is adapted to the cross-sectional shape of the first guide rod 23, so that the first guide rod 23 and the first support member 21 do not rotate relative to each other, so that when the first rod 222 rotates, the first support member 21 can move upward or downward.

[0068] By setting the cross-section of the first guide rod 23 to be non-circular and the cross-section of the first guide hole 213 to match the cross-sectional shape of the first guide rod 23, the first guide rod 23 and the first support member 21 do not rotate relative to each other. The cross-section of the first guide rod 23 and the cross-sectional shape of the first guide hole 213 are regular, and the first guide rod 23 and the first guide hole 213 extend in the up and down directions, with a regular shape and a simple structure, which is convenient for processing and assembly.

[0069] By the first support rod 211 being sleeved on the first guide rod 23 through the first guide hole 213 , the first support rod 211 can move stably and reliably with high operating precision.

[0070] According to some embodiments of the utility model, the first lifting mechanism 20 also includes: a first limiting member, which is arranged on the first guide rod 23 and extends radially outward along the first guide rod 23, and a first limiting hole 214 is formed on the first support member 21, and the first limiting hole 214 extends up and down, and the first limiting member can be slidably engaged in the first limiting hole 214 up and down.

[0071] Reference Figure 2-Figure 4 As shown, the first limit member is fixed on the first guide rod 23. When the first transmission member 22 rotates to drive the first support member 21 to move upward until the lower end surface of the first limit hole 214 contacts the first limit member, at this time, due to the limiting stop effect of the first limit member, the first support member 21 stops moving upward; when the first transmission member 22 drives the first support member 21 to move downward until the upper end surface of the first limit hole 214 contacts the first limit member, due to the limiting stop effect of the first limit member, the first support member 21 stops moving downward, and the first limit member moves relatively in the first limit hole 214 along the up and down directions, which can limit the moving distance of the first support member 21 in the up and down directions, and prevent the first support member 21 from detaching from the first guide rod 23.

[0072] Furthermore, the first limit member is fixed on the first guide rod 23. For example, a first fixing hole 231 is formed on the first guide rod 23. The first limit member is columnar and extends radially along the first guide rod 23. One end of the first limit member is fixed in the first fixing hole 231, and the other end of the first limit member is passed through the first limit hole 214.

[0073] In order to facilitate the assembly of the first limit member to the first guide rod 23, an assembly avoidance hole 223 is formed on the first rod 222. During assembly, the first limit member extends from the assembly avoidance hole 223 into the first rod 222 to be inserted into the first fixing hole 231 of the first guide rod 23.

[0074] According to some embodiments of the utility model, the first support member 21 includes: a first support rod 211 and a first sleeve rod 212, the first support rod 211 extends vertically, an external thread is formed on the outer surface of the lower end of the first support rod 211, and the first sleeve rod 212 is sleeved on the outer side of the upper end of the first support rod 211 and fixed to the first support rod 211.

[0075] The upper edge of the first support rod 211 extends upward beyond the upper edge of the first sleeve rod 212 , and a support groove 215 is formed between the inner wall surface of the upper end of the first sleeve rod 212 and the outer peripheral surface of the upper end of the first support rod 211 , and the support groove 215 forms a first support portion.

[0076] Reference Figure 8As shown, the first sleeve rod 212 is located on the first support rod 211, located on the upper part of the first support rod 211, sleeved on the outer side of the upper end of the first support rod 211 and fixed, the upper end edge of the first support rod 211 is higher than the upper end edge of the first sleeve rod 212, and a supporting groove 215 is formed between the inner wall surface of the upper end of the first sleeve rod 212, the outer peripheral surface of the upper end of the first support rod 211 and the upper surface of the lower side plate of the first sleeve rod 212, so that the first sleeve rod 212 can be sleeved on the upper shaft gear assembly 200 or the lower shaft gear assembly 300. Specifically, the lower end faces of the upper shaft gear assembly 200 and the lower shaft gear assembly 300 are in contact with the bottom wall of the support groove 215, and the bottom wall of the support groove 215 limits the position of the upper shaft gear assembly 200 and the lower shaft gear assembly 300 in the up and down directions, thereby playing a limiting role. The outer peripheral surfaces of the lower sides of the upper shaft gear assembly 200 and the lower shaft gear assembly 300 are in contact with the side walls of the support groove 215, and the side walls of the support groove 215 can keep the upper shaft gear assembly 200 and the lower shaft gear assembly 300 in a vertical state, thereby preventing the upper shaft gear assembly 200 and the lower shaft gear assembly 300 from colliding with adjacent components.

[0077] By arranging the first sleeve rod 212 on the upper part of the first support rod 211, the support groove 215 formed inside the first sleeve rod 212 cooperates with the upper shaft gear assembly 200 and the lower shaft gear assembly 300, so that the first sleeve rod 212 can be connected with the upper shaft gear assembly 200 and the lower shaft gear assembly 300 more firmly and stably, and the inner wall surface of the support groove 215 contacts the outer peripheral surface of the lower side of the upper shaft gear assembly 200 and the lower shaft gear assembly 300, and the contact area is large, which can better keep the upper shaft gear assembly 200 and the lower shaft gear assembly 300 in a vertical state. In addition, the first sleeve rod 212 is a rod-shaped structure, which is simple in structure and easy to process.

At the same time, the first driving member 31 can drive the two first lifting mechanisms 20, so that the upper shaft gear assembly 200 and the lower shaft gear assembly 300 can be lifted and lowered synchronously, and then the upper shaft gear assembly 200 and the lower shaft gear assembly 300 can be lifted and lowered synchronously, thereby improving the assembly efficiency; avoiding the upper shaft gear assembly 200 and the lower shaft gear from colliding with each other and damaging the gears; compared with the traditional assembly method that requires multiple people to coordinate the assembly, the use of the transmission assembly tool 100 is conducive to reducing the difficulty of assembly.

[0081] Reference Figure 2 As shown, the transmission assembly tool 100 has a second lifting mechanism 40, which is located on the upper side of the base 10. The second lifting mechanism 40 includes a second support member 41 and a second transmission member 42. The second transmission member 42 is connected to the second support member 41. The second transmission member 42 drives the second support member 41 to move in the up and down directions. The second support member 41 has a second support portion, which is located in the upper area of ​​the second support member 41. The second support portion is connected to the internal shaft gear assembly 400, so that the second support portion can adjust the position of the internal shaft gear assembly 400 in the up and down directions by lifting and lowering the second support member 41.

[0082] Preferably, the second supporting portion is a concave groove formed on the upper end surface of the second supporting member 41 .

The second support portion located on the second support member 41 is connected to the internal shaft gear assembly 400, so that the internal shaft gear assembly 400 can move in the up and down directions.

[0084] The transmission assembly tool 100 is placed on the workbench, the first driving member 31 is driven, the two first supporting members 21 and the second supporting members 41 are adjusted to a suitable height, the transmission housing 500 is placed on the transmission assembly tool 100, and the first supporting members 21 and the second supporting members 41 pass through the corresponding holes on the housing 500. Place the differential assembly on the housing 500, place the upper shaft gear assembly 200, the lower shaft gear assembly 300 and the inner shaft gear assembly 400 on the two first support members 21 and the second support member 41 respectively, and pre-install the upper shaft gear assembly 200, the lower shaft gear assembly 300 and the inner shaft gear assembly 400; drive the first driving member 31, and the first driving member 31 drives the first transmission member 22 and the second transmission member 42, so that the first support member 21 and the second support member 41 descend, thereby driving the upper shaft gear assembly 200, the lower shaft gear assembly 300 and the inner shaft gear assembly 400 to descend, so as to assemble the upper shaft gear assembly 200, the lower shaft gear assembly 300 and the inner shaft gear assembly 400 to the predetermined position, thereby completing the assembly.

[0085] According to some embodiments of the utility model, the second transmission member 42 includes: a second rod 422 and a second gear 421, the second rod 422 is coaxially fixed with the second gear 421, and the second rod 422 is threadedly engaged with the second support member 41, the first driving member 31 is a driving gear, the driving gear is engaged with the second gear 421 for driving the second gear 421 to rotate, and the first gear 221 is engaged with the second gear 421.

[0086] Reference Figure 2 and Figure 5 As shown, the second transmission member 42 includes a second rod 422 and a second gear 421. The second rod 422 and the second gear 421 are coaxially fixed, so that the second rod 422 can obtain the same rotation speed as the second gear 421. The first driving member 31 is a driving gear, and the first driving member 31 is engaged with the second gear 421, so that the first driving member 31 can drive the second gear 421 to rotate, thereby making the second rod 422 and the second gear 421 rotate at the same speed. Since the second rod 422 is threadedly engaged with the second support member 41, the second rod 422 and the second support member 41 can move relative to each other in the up and down directions.

[0087] The first driving member 31 is meshed with the second gear 421. The rotation of the first driving member 31 drives the second gear 421 to rotate. At the same time, the second rod 422 rotates, so that the support member can move in the up and down directions, driving at least one of the upper shaft gear assembly 200 and the lower shaft gear assembly 300 to move in the up and down directions.

[0088] By adopting gear transmission between the first driving member 31 and the second gear 421, the transmission accuracy and efficiency of the first driving member 31 and the second gear 421 can be high, the transmission process of the first driving member 31 and the second gear 421 can be stable, and the compact structure of the first driving member 31 and the second gear 421 can also make the maintenance of the first driving member 31 and the second gear 421 simple, thereby better controlling the movement of the internal shaft gear assembly 400 in the up and down directions.

[0089] By setting the second support member 41 and the second rod 422 to be threadedly engaged, the rotational movement of the second rod 422 can be transmitted to the second support member 41, so that the second support member 41 moves in a straight line. The threaded engagement structure of the second support member 41 and the second rod 422 is simple, which is convenient for the processing and production of the second support member 41 and the second rod 422. The threaded transmission between the second support member 41 and the second rod 422 has high precision and high stability.

[0090] Preferably, a plurality of second weight-reducing holes 4211 are formed on the second gear 421 .

[0091] According to some embodiments of the utility model, the second rod 422 is a hollow column, an internal thread is formed on the inner circumferential wall of the second rod 422, the second support member 41 is a rod-shaped extending up and down, an external thread that matches the internal thread of the second rod 422 is formed on the outer circumferential surface of the second support member 41, and the second rod 422 is sleeved on the radial outer side of the second support member 41 and is connected to the second support member 41 through the internal thread to drive the second support member 41 to move up and down.

[0092] Reference Figure 2 and Figure 5 As shown, the second rod 422 is a hollow column extending in the up-down direction, with an internal thread formed on the inner peripheral wall, and the second support member 41 is a rod extending up-down, with an external thread formed on the outer peripheral surface, and the second rod 422 is located outside the second support member 41, so that the second rod 422 and the second support member 41 can rotate relative to each other, and through threaded engagement, the second rod 422 and the second support member 41 can move relative to each other in the up-down direction.

[0093] The first driving member 31 is meshed with the second gear 421. The rotation of the first driving member 31 drives the second gear 421 to rotate. At the same time, the second rod 422 rotates. The internal thread of the inner circumferential wall of the second rod 422 is meshed with the external thread of the second support member 41, so that the second support member 41 can move in the up and down direction, driving at least one of the internal shaft gear assemblies 400 to move in the up and down direction, so as to assemble the internal shaft gear assembly 400 to a predetermined position.

[0094] By setting the second rod 422 to be a hollow column and the second support member 41 to be a rod extending up and down, the second support member 41 can be moved in a straight line. At the same time, the second rod 422 provides a receiving space for the second support member 41 and has a guiding function.

[0095] By setting the internal thread of the inner circumferential wall of the second rod 422 to engage with the external thread of the second support member 41, the rotational movement of the second rod 422 can be transmitted to the second support member 41, so that the second support member 41 moves in a straight line. The threaded engagement structure of the second support member 41 and the second rod 422 is simple, which is convenient for the processing and production of the second support member 41 and the second rod 422. The threaded transmission between the second support member 41 and the second rod 422 has high precision and high stability.

[0096] According to some embodiments of the utility model, the second lifting mechanism 40 also includes: a second guide rod 43, the second guide rod 43 extends vertically, the lower end of the second guide rod 43 is fixed to the base 10, the second support member 41 is a hollow rod and defines a second guide hole 412 on the inner side, the second support member 41 is sleeved on the second guide rod 43 through the second guide hole 412, wherein the cross-section of the second guide rod 43 is non-circular, and the cross-section of the second guide hole 412 is adapted to the cross-sectional shape of the second guide rod 43.

[0097] Reference Figure 2-Figure 9 - Fig.10 As shown, the second support member 41 is located outside the second guide rod 43, and the second support member 41 is sleeved on the second guide rod 43 through the second guide hole 412. The second guide rod 43 and the second support member 41 both extend vertically, so that the second guide rod 43 and the second support member 41 can move relative to each other in the up and down directions.

[0098] The lower end of the second guide rod 43 is fixed to the base 10. For example, the base 10 is formed with a second threaded hole 12, and the lower end of the second guide rod 43 extends into the second threaded hole 12 and is threadedly connected to the base 10. In this way, the second guide rod 43 can be prevented from moving relative to the base 10 and the second transmission member 42 can rotate around the second guide rod 43. The cross section of the second guide rod 43 is non-circular, such as rectangular, triangular, pentagonal, trapezoidal and hexagonal. The cross section of the second guide hole 412 is adapted to the cross-sectional shape of the second guide rod 43, so that the second guide rod 43 and the second support member 41 do not rotate relative to each other, so that when the second rod 422 rotates, the second support member 41 can move upward or downward.

[0099] By setting the cross-section of the second guide rod 43 to be non-circular and the cross-section of the second guide hole 412 to match the cross-sectional shape of the second guide rod 43, the second guide rod 43 and the second support member 41 can be prevented from relative rotation. The cross-section of the second guide rod 43 and the cross-sectional shape of the second guide hole 412 are regular, and the second guide rod 43 and the second guide hole 412 extend in the up and down directions, with a regular shape and a simple structure, which is convenient for processing and assembly.

[0100] By the second support rod 411 being sleeved on the second guide rod 43 through the second guide hole 412 , the second support rod 411 can move stably and reliably with high operating precision.

[0101] According to some embodiments of the utility model, the second lifting mechanism 40 also includes: a second limiting member, which is arranged on the second guide rod 43 and extends radially outward along the second guide rod 43, and a second limiting hole is formed on the second support member 41, and the second limiting hole extends up and down, and the second limiting member can be slidably engaged in the second limiting hole up and down.

[0102] Specifically, the second limit member is fixed on the second guide rod 43. When the second transmission member 42 rotates to drive the second support member 41 to move upward until the lower end surface of the second limit hole contacts the second limit member, at this time, due to the limiting stop effect of the second limit member, the second support member 41 stops moving upward; when the second transmission member 42 drives the second support member 41 to move downward until the upper end surface of the second limit hole contacts the second limit member, due to the limiting stop effect of the second limit member, the second support member 41 stops moving downward, and the second limit member moves relatively in the second limiting hole along the up and down directions, which can limit the moving distance of the second support member 41 in the up and down directions, and prevent the second support member 41 from detaching from the second guide rod 43.

[0103] Furthermore, the second limit member is fixed on the second guide rod 43. For example, a second fixing hole is formed on the second guide rod 43. The second limit member is columnar and extends radially along the second guide rod 43. One end of the second limit member is fixed in the second fixing hole, and the other end of the second limit member is passed through the second limit hole.
