[0036] Figure 1 And Figure 2 The utility model discloses a spray gun assembly 100, spray gun assembly 100 includes fixed frame 102, movable frame 101, spray gun 103, motor unit 105, first transmission mechanism 109, first clutch mechanism 107 and second clutch mechanism 108.

[0037] Figure 3 It is the explosion map of spray gun assembly 100, in this embodiment, movable frame 101 includes first shell piece 112, second shell piece 113 and third shell piece 114, the three shell pieces are connected by screw.The main part of first clutch mechanism 107, second clutch mechanism 108 is located between third shell piece 114 and second shell piece 113, and the main part of first transmission mechanism 109 and second transmission mechanism 110 is located between first shell piece 112 and second shell piece 113.In other embodiments, the number contained in movable frame 101 can also be appropriately increased or decreased, as long as movable frame 101 can provide enough mounting position, which will not be described in detail here.Movable frame 101 is movably connected with fixed frame 102, and movable frame 101 can move relative to fixed frame 102.The spray gun assembly 100 of the utility model can be applied in the toilet, and fixed frame 102 can be fixed with the toilet body, and movable frame 101 can move relative to the toilet.For example, as shown in Figure 8 In this embodiment, movable frame 101 can swing relative to fixed frame 102.

[0038] Spray gun 103 is movably connected with movable frame 101, and spray gun 103 can move relative to movable frame 101.For example, as shown in Figure 4 And Figure 6 In this embodiment, spray gun 103 can move linearly relative to movable frame 101.As shown in Figure 1As shown, the spray gun 103 is provided with a water outlet 104, which is arranged upwardly, and water for cleaning the user's body can be sprayed from the water outlet 104. The spray gun 103 is also provided with a water inlet, which is not shown in the figure, and the water inlet and the water outlet 104 can be arranged at two ends of the spray gun 103, respectively. For example, the water outlet 104 is arranged at the front end of the spray gun 103, and the water inlet is arranged at the rear end of the spray gun 103, and the water inlet is connected with a pipeline for supplying water.

[0039] As shown in Figure 2 , the first transmission mechanism 109 is mounted on the movable frame 101, and the first transmission mechanism 109 is connected with the spray gun 103. The motor unit 105 and the first clutch mechanism 107 are both mounted on the movable frame 101, and the first clutch mechanism 107 is connected with the motor unit 105. When the first clutch mechanism 107 and the first transmission mechanism 109 are in transmission with each other, the power output by the motor unit 105 can be sequentially transmitted to the first clutch mechanism 107, the first transmission mechanism 109 and the spray gun 103, and the motor unit 105 drives the spray gun 103 to make a first movement relative to the movable frame 101. The first movement of the spray gun 103 can be a linear movement of the spray gun 103 relative to the movable frame 101 (as shown in Figure 4 and Figure 6 ).

[0040] As shown in Figure 2 , a part of the second transmission mechanism 110 is mounted on the movable frame 101, and another part of the second transmission mechanism 110 is mounted on the fixed frame 102. The second clutch mechanism 108 is mounted on the movable frame 101, and the second clutch mechanism 108 is connected with the motor unit 105. When the second clutch mechanism 108 and the second transmission mechanism 110 are in transmission with each other, the power output by the motor unit 105 can be sequentially transmitted to the second clutch mechanism 108 and the second transmission mechanism 110, and the motor unit 105 drives the movable frame 101 and the spray gun 103 to make a second movement relative to the fixed frame 102 synchronously. The second movement of the spray gun 103 and the movable frame 101 can be a swinging movement of the spray gun 103 and the movable frame 101 relative to the fixed frame 102 synchronously (as shown in Figure 8 ).

[0041] The movement axis of the first movement and the movement axis of the second movement intersect. The intersection of the two movement axes means that the two movement axes are not parallel and not coincident, that is, the included angle between the two movement axes can be an acute angle, an obtuse angle or a right angle. For example, as shown in Figure 6As shown, when the spray gun 103 is in the first motion, the spray gun 103 is slidably arranged in the first guide slot 145 of the movable frame 101, the first guide slot 145 and the spray gun 103 are straight, the center line of the first guide slot 145 is the first axis 146, the spray gun 103 can move linearly along the first axis 146, and the first axis 146 is the motion axis of the first motion. When the spray gun 103 is in the second motion, the spray gun 103 swings around the second axis 147, and the second axis 147 is the motion axis of the second motion. The included angle between the first axis 146 and the second axis 147 is an acute angle, so as to meet the condition that the motion axis of the first motion and the motion axis of the second motion intersect. Of course, in other embodiments, the included angle between the first axis 146 and the second axis 147 can also be a right angle or an obtuse angle.

[0042] In the embodiment, the first motion is used to extend and retract the spray gun 103 relative to the movable frame 101. After the spray gun 103 is extended, the water outlet 104 of the spray gun 103 discharges water and performs body washing on the user; after the washing is completed, the spray gun 103 is retracted. The second motion is used to expand the washing area of the water flow. During the washing process, as the spray gun 103 swings, the tail end of the water flow discharged from the water outlet 104 also moves to form a fan-shaped washing area. It should be noted that in other embodiments not shown, the first motion and the second motion can also be both linear motions. The second motion set as a linear motion can also expand the washing area of the water flow, and at this time, the washing area of the water flow is approximately rectangular.

[0043] For the spray gun assembly 100 of the utility model, by switching the states of the first clutch mechanism 107 and the second clutch mechanism 108, the driving object of the motor unit 105 can be changed. The same motor unit 105 can drive the spray gun 103 to make the first motion through the first transmission mechanism 109, and can also drive the spray gun 103 to make the second motion through the second transmission mechanism 110. In this way, the two different motions of the spray gun 103 can be realized through one motor unit 105, and the number of motor units 105 required by the spray gun assembly 100 is less, which is conducive to reducing the number of motor units 105, thereby being conducive to reducing the cost of the spray gun assembly 100 and the toilet.

[0044] In some embodiments, the motor unit 105 comprises a rotatable motor shaft 131. The motor shaft 131 is rotatable in a first reference direction, so as to enable the first clutch mechanism 107 and the first transmission mechanism 109 to transmit power to each other, and to disconnect the power transmission between the second clutch mechanism 108 and the second transmission mechanism 110. The motor shaft 131 is also rotatable in a second reference direction, so as to enable the second clutch mechanism 108 and the second transmission mechanism 110 to transmit power to each other, and to disconnect the power transmission between the first clutch mechanism 107 and the first transmission mechanism 109. The first reference direction and the second reference direction are opposite to each other, for example, the first reference direction is counterclockwise, and the second reference direction is clockwise.

[0045] In the above arrangement, when the motor shaft 131 rotates in a forward direction, the spray gun 103 performs the first movement; when the motor shaft 131 rotates in a reverse direction, the spray gun 103 performs the second movement. By controlling the rotation direction of the motor shaft 131, the power transmission between the first clutch mechanism 107 and the first transmission mechanism 109, and the power transmission between the second clutch mechanism 108 and the second transmission mechanism 110 can be automatically controlled, so as to control the movement mode of the spray gun 103. The above control method does not require complex sensors and controllers, and is conducive to reducing the control difficulty and cost of the spray gun assembly 100.

[0046] The specific structure of the motor unit 105, the first clutch mechanism 107 and the second clutch mechanism 108 will be described below, so as to illustrate how to achieve the above functions.

The first clutch mechanism 107 is arranged between the motor unit 105 and the first transmission mechanism 109, and the second clutch mechanism 108 is arranged between the motor unit 105 and the second transmission mechanism 110. The first transmission mechanism 109 and the second transmission mechanism 110 are arranged in parallel with each other, and the first clutch mechanism 107 and the second clutch mechanism 108 are arranged in parallel with each other. Figure 10 As shown in FIG. 1, the spray gun assembly 100 comprises a motor unit 105, a first transmission mechanism 109, a second transmission mechanism 110, a first clutch mechanism 107 and a second clutch mechanism 108. The motor unit 105 is arranged on the movable frame 101, and the first transmission mechanism 109 and the second transmission mechanism 110 are arranged on the movable frame 101. The first clutch mechanism 107 is arranged between the motor unit 105 and the first transmission mechanism 109, and the second clutch mechanism 108 is arranged between the motor unit 105 and the second transmission mechanism 110.

The second ratchet 129 includes a plurality of second ratchet teeth 149, and the second ratchet 129 is provided with a second ratchet tooth 149 at one end in its own axial direction. The movable frame 101 and the first gear 133 are both connected to the first elastic member 134. The elastic force of the first elastic member 134 is used to keep the first ratchet 132 and the second ratchet 129 engaged, and to restore the first ratchet 132 and the second ratchet 129 to mesh. Figure 3 As shown, the third housing 114 has a first mounting groove 135, and the first elastic member 134 is accommodated in the first mounting groove 135.

[0049] The shapes of the first ratchet teeth 148 and the second ratchet teeth 149 are as follows: Figure 9 As shown. The two side surfaces of the first ratchet tooth 148 are a first straight surface 150 and a first inclined surface 151, respectively. The normal of the first straight surface 150 is perpendicular to the central axis of the first ratchet 132, and the normal of the first straight surface 150 and the central axis of the first ratchet 132 do not intersect.

[0050] If the tooth groove formed by two adjacent first ratchet teeth 148 is called the first tooth groove, and the tooth groove formed by two adjacent second ratchet teeth 149 is called the second tooth groove, then the mutual engagement of the first ratchet 132 and the second ratchet 129 means that: a second ratchet tooth 149 is provided in each first tooth groove, a first ratchet tooth 148 is provided in each second tooth groove, and the first straight surface 150 and the second straight surface 152 are arranged opposite to each other, and the first inclined surface 151 and the second inclined surface 153 are arranged opposite to each other.

[0051] Figure 10 1 shows the state of the first clutch mechanism 107 when the motor shaft 131 rotates along the first reference direction. Figure 11The state of the second clutch mechanism 108 when the motor shaft 131 rotates along the second reference direction is shown. In the description of Figure 10 and Figure 11 , both the clockwise direction and the counterclockwise direction are based on the perspective of viewing from top to bottom. It should be noted that, for the convenience of description of the first clutch mechanism 107 and the second clutch mechanism 108, Figures 9 to 11 the directions marked do not correspond to the directions of other drawings. If the directions of the drawings are to be unified, then Figures 9 to 11 the up-down direction marked corresponds to the left-right direction in other drawings.

[0052] As shown in Figure 10 , when the motor shaft 131 rotates along the counterclockwise direction (the first reference direction), the first gear 133 and the first ratchet wheel 132 rotate along the clockwise direction correspondingly. In the process of the clockwise rotation of the first ratchet wheel 132, the first straight surface 150 and the second straight surface 152 abut against each other, the first ratchet wheel 132 does not move axially, the first ratchet wheel 132 and the second ratchet wheel 129 remain engaged, the first ratchet wheel 132 pushes the second ratchet wheel 129 to rotate, thereby causing the first gear 133, the first ratchet wheel 132, the second ratchet wheel 129 and the first input wheel 121 to rotate along the clockwise direction synchronously.

[0053] As shown in Figure 11 , when the motor shaft 131 rotates along the clockwise direction (the second reference direction), the first gear 133 and the first ratchet wheel 132 rotate along the counterclockwise direction correspondingly. When the first ratchet wheel 132 just starts to rotate counterclockwise, the first inclined surface 151 abuts against the second inclined surface 153, but since the first input wheel 121 can only rotate along the clockwise direction unidirectionally, and the first input wheel 121 and the second ratchet wheel 129 are fixed to each other, the first ratchet wheel 132 cannot push the second ratchet wheel 129 to rotate counterclockwise. Moreover, the second ratchet wheel 129 is fixed axially by itself, and the second ratchet wheel 129 does not move relative to the movable frame 101 in the axial direction. The force exerted by the second inclined surface 153 on the first inclined surface 151 has a downward component, which pushes the first ratchet wheel 132 to move downward and causes the first ratchet wheel 132 to gradually move away from the second ratchet wheel 129, while the first elastic member 134 is gradually compressed. As the first ratchet wheel 132 gradually moves away from the second ratchet wheel 129, the first ratchet wheel 132 and the second ratchet wheel 129 disengage. Subsequently, as the first ratchet wheel 132 continues to rotate, the first ratchet teeth 148 will again align with the second tooth grooves, and under the elastic force of the first elastic member 134, the first ratchet wheel 132 moves axially and resets (moves upward), and the engagement between the first ratchet wheel 132 and the second ratchet wheel 129 is restored. In the process of the rotation of the first ratchet wheel 132, the above process is repeated continuously.

[0054] In this way, when the motor shaft 131 rotates in the clockwise direction (the second reference direction), the first ratchet wheel 132 not only rotates but also reciprocates along its axial direction, and the first ratchet wheel 132 and the second ratchet wheel 129 are periodically disengaged and re-engaged. However, during the clockwise rotation of the motor shaft 131, the second ratchet wheel 129 and the first input wheel 121 are stationary regardless of whether the first ratchet wheel 132 and the second ratchet wheel 129 are engaged, and the spray gun 103 does not perform the first movement. The axial movement of the first ratchet wheel 132 is mainly to prevent the stationary second ratchet wheel 129 from jamming the first ratchet wheel 132, so that the first ratchet wheel 132, the output gear 106, and the motor shaft 131 can still rotate smoothly, thereby ensuring that the motor shaft 131, the second clutch mechanism 108, and the second transmission mechanism 110 can achieve transmission.

[0055] As mentioned above, the first input wheel 121 can only rotate in one direction. As shown in Figure 4 the first input wheel 121 can be a ratchet wheel, and accordingly, the first transmission mechanism 109 further includes a first pawl 122 movably mounted to the movable frame 101, the first pawl 122 being connected to the first input wheel 121 so that the first input wheel 121 can only rotate in one direction. More specifically, the top end of the first pawl 122 is rotationally connected to the movable frame 101, and the bottom end of the first pawl 122 is used to connect with the ratchet wheel, and the first transmission mechanism 109 further includes a third elastic member 123, both ends of the third elastic member 123 being connected to the movable frame 101 and the first pawl 122, respectively, and the elastic force of the third elastic member 123 is used to make the first pawl 122 clamped between the two ratchet teeth of the first input wheel 121. When the first input wheel 121 rotates clockwise, the ratchet teeth of the first input wheel 121 can push the first pawl 122 away, and the first pawl 122 does not hinder the clockwise rotation of the first input wheel 121. When the first input wheel 121 rotates counterclockwise, the ratchet teeth of the first input wheel 121 cannot push the first pawl 122 away, and the first pawl 122 hinders the counterclockwise rotation of the first input wheel 121.

[0056] In other embodiments not shown, the connection between the bottom end of the first pawl 122 and the first input wheel 121 can also be maintained by magnetic force or the gravity of the first pawl 122 itself. In addition, in other embodiments not shown, the one-way rotation function can also be achieved without using a pawl. Instead, the first input wheel 121 can be connected to the movable frame 101 through a one-way bearing, and accordingly, the first input wheel 121 does not need to be provided as a ratchet wheel.

[0057] The structure and principle of the second clutch mechanism 108 are similar to those of the first clutch mechanism 107. As shown in Figure 10As shown, the second transmission mechanism 110 comprises a second input wheel 127 which rotates in one direction only, when the second input wheel 127 rotates relative to the movable frame 101, the spray gun 103 makes the second movement. The second clutch mechanism 108 comprises a second gear 137, a third ratchet wheel 136, a fourth ratchet wheel 128 and a second elastic member 138. The second gear 137 is mounted on the movable frame 101, and the second gear 137 is engaged with the output gear 106. The second gear 137 is fixed with the third ratchet wheel 136 and coaxially arranged, the third ratchet wheel 136 comprises a plurality of third ratchet teeth 154, and the third ratchet wheel 136 is provided with the third ratchet teeth 154 at one end in the axial direction of the third ratchet wheel 136. The fourth ratchet wheel 128 is fixed with the second input wheel 127 and coaxially arranged, the fourth ratchet wheel 128 comprises a plurality of fourth ratchet teeth 155, and the fourth ratchet wheel 128 is provided with the fourth ratchet teeth 155 at one end in the axial direction of the fourth ratchet wheel 128. The shape of the third ratchet teeth 154 and the shape of the fourth ratchet teeth 155 can refer to the shape of the first ratchet teeth 148 and the shape of the second ratchet teeth 149 described above, and will not be described here. The movable frame 101 and the second gear 137 are connected with the second elastic member 138. For example, as shown in Figure 3 As shown, the third housing 114 is provided with a second mounting groove 139, and the second elastic member 138 is accommodated in the second mounting groove 139. One end of the second elastic member 138 abuts against the wall surface of the second mounting groove 139, and the other end of the second elastic member 138 abuts against the second gear 137. The elastic force of the second elastic member 138 is used to keep the third ratchet wheel 136 and the fourth ratchet wheel 128 engaged, and to restore the engagement of the third ratchet wheel 136 and the fourth ratchet wheel 128. The fourth ratchet wheel 128 is also fixed relative to the movable frame 101 in the axial direction of the fourth ratchet wheel 128, and the fourth ratchet wheel 128 cannot move in the axial direction of the fourth ratchet wheel 128.

[0058] As shown in Figure 11 When the motor shaft 131 rotates in the second reference direction (clockwise direction), the third ratchet wheel 136 and the fourth ratchet wheel 128 keep engaging with each other, and the second gear 137, the third ratchet wheel 136, the fourth ratchet wheel 128 and the second input wheel 127 rotate synchronously (rotate synchronously in the counterclockwise direction). Accordingly, at this time, the spray gun 103 makes the second movement.

[0059] As shown in Figure 10 When the motor shaft 131 rotates in the first reference direction (counterclockwise direction), based on the matching relationship of the third ratchet wheel 136 and the fourth ratchet wheel 128, the third ratchet wheel 136 rotates and reciprocates in the axial direction of the third ratchet wheel 136, the third ratchet wheel 136 and the fourth ratchet wheel 128 periodically disengage and engage with each other, and the fourth ratchet wheel 128 and the second input wheel 127 are stationary. At this time, the spray gun 103 does not make the second movement.

[0060] The axial movement of the third ratchet 136 is mainly to prevent the stationary fourth ratchet 128 from locking the third ratchet 136, so that the third ratchet 136, the output gear 106 and the motor shaft 131 can still rotate smoothly. At this time, since the motor shaft 131 can still be actuated, the transmission between the motor shaft 131, the first clutch mechanism 107 and the first transmission mechanism 109 can be achieved.

[0061] As shown in Figure 5 The second input wheel 127 can also be provided as a ratchet, and the second transmission mechanism 110 further includes a second pawl 125 movably mounted to the movable frame 101, the second pawl 125 being connected to the second input wheel 127 to enable the second input wheel 127 to rotate in one direction. The fourth elastic member 124 has two ends connected to the movable frame 101 and the second pawl 125, respectively, and the elastic force of the fourth elastic member 124 is used to enable the second pawl 125 to be clamped between two ratchet teeth of the second input wheel 127. In other embodiments not shown, a pawl can also be used to achieve the function of one-way rotation; instead, the second input wheel 127 can be connected to the movable frame 101 through a one-way bearing, in which case the second input wheel 127 does not need to be provided as a ratchet.

[0062] The structure and principle of the first transmission mechanism 109 and the second transmission mechanism 110 will be introduced below.

[0063] As shown in Figure 4 The spray gun 103 is slidably connected to the movable frame 101, and the spray gun 103 is slidably arranged in a first guide slot 145 of the movable frame 101. The first guide slot 145 is straight, so the first movement is a linear movement. The first transmission mechanism 109 can include a first connecting rod 117, a second connecting rod 118, a linking gear 119, a first rack 120 and a second rack 111. The first connecting rod 117 includes a first end and a second end, and the second connecting rod 118 includes a third end and a fourth end. In Figure 4In the embodiment shown in the drawings, the first end is the rear end of the first connecting rod 117, the second end is the front end of the first connecting rod 117, the third end is the rear end of the second connecting rod 118, and the fourth end is the front end of the second connecting rod 118. The first end is rotatably connected to the first input wheel 121, and the first end is arranged at a distance from the rotation axis of the first input wheel 121. The third end is rotatably connected to the second end, and the adapter gear 119 is rotatably mounted on the fourth end. The second connecting rod 118 is slidably connected to the movable frame 101, and the second connecting rod 118 can slide along its length direction, and the second connecting rod 118 is parallel to the spray gun 103. For example, the movable frame 101 is further provided with a second guide slot (not shown), the second guide slot is parallel to the first guide slot 145, and the second connecting rod 118 is arranged in the second guide slot. The first rack 120 and the second rack 111 are engaged with the adapter gear 119. The first rack 120 is fixed to the movable frame 101, the second rack 111 is fixed to the spray gun 103, the first rack 120 and the second rack 111 are arranged opposite to each other, and the extension direction of the first rack 120 is the same as the extension direction of the second rack 111. When the first input wheel 121 rotates, the spray gun 103 can make a first movement, and the spray gun 103 can be extended forward and retracted backward.

[0064] As described above, the first input wheel 121 can only rotate in one direction. When the first input wheel 121 rotates clockwise and rotates from the angle shown in FIG. 6A to the angle shown in FIG. 6B, Figure 6 When the first input wheel 121 rotates clockwise and rotates from the angle shown in FIG. 6A to the angle shown in FIG. 6B, Figure 4 The second connecting rod 118 pushes the adapter gear 119 to move forward. When the adapter gear 119 moves forward, it also rotates relative to the second connecting rod 118, thereby driving the second rack 111 and the spray gun 103 to move forward. In the process that the first input wheel 121 rotates clockwise and rotates from the angle shown in FIG. 6A to the angle shown in FIG. 6B, Figure 4 When the first input wheel 121 rotates clockwise and rotates from the angle shown in FIG. 6A to the angle shown in FIG. 6B, Figure 6 The second connecting rod 118 pushes the adapter gear 119 to move forward. When the adapter gear 119 moves forward, it also rotates relative to the second connecting rod 118, thereby driving the second rack 111 and the spray gun 103 to move forward. In the process that the first input wheel 121 rotates clockwise and rotates from the angle shown in FIG. 6A to the angle shown in FIG. 6B,

[0065] The first transmission mechanism 109 described above makes the stroke of the spray gun 103 twice the moving stroke of the adapter gear 119, which is beneficial to increase the movement stroke of the spray gun 103 and is suitable for a longer spray gun 103.

[0066] In other embodiments not shown in the drawings, in order to reduce the number of parts and cost of the first transmission mechanism 109, the first transmission mechanism 109 can also only include one connecting rod, the first end of the connecting rod is rotatably connected to the first input wheel 121, the first end is arranged at a distance from the rotation axis of the first input wheel 121, and the second end is rotatably connected to the spray gun 103. This design is equivalent to combining the first connecting rod 117 and the second connecting rod 118 into one connecting rod. Figure 4The second connecting rod 118, the first rack 120, the second rack 111 and the engaging gear 119 in the first embodiment are omitted, and the front end of the first connecting rod 117 is directly connected with the spray gun 103. This design can also convert the rotation of the first input wheel 121 into the linear motion of the spray gun 103.

[0067] In the case where the second motion is the swinging motion, as shown in Figure 7 The second transmission mechanism 110 can include a first bevel gear 126, a second bevel gear 140 and a slide bar 141. The first bevel gear 126 and the second bevel gear 140 are both mounted on the movable frame 101, and the slide bar 141 is mounted on the fixed frame 102. The first bevel gear 126 is coaxially arranged with the second input wheel 127. The second bevel gear 140 is engaged with the first bevel gear 126, and the slide bar 141 is coaxially arranged with the second bevel gear 140. The slide bar 141 is eccentrically arranged relative to the second bevel gear 140, i.e. the central axis of the slide bar 141 is parallel to the central axis of the second bevel gear 140. The fixed frame 102 is provided with a straight sliding groove 143, and the slide bar 141 is slidably arranged in the sliding groove 143.

[0068] The movable frame 101 is rotationally connected with the fixed frame 102. As shown in Figure 3 The first housing 112 of the movable frame 101 is provided with a pin shaft part 115 and a mounting hole 116, and the fixed frame 102 is provided with a shaft hole 142. The pin shaft part 115 is rotatably arranged in the shaft hole 142, and the central axis of the pin shaft part 115 or the shaft hole 142 is the second axis 147. The second bevel gear 140 is mounted in the mounting hole 116.

[0069] When the second input wheel 127 rotates, the first bevel gear 126 and the second bevel gear 140 also rotate. Since the second input wheel 127 can only rotate in one direction, the first bevel gear 126 and the second bevel gear 140 can also only rotate in one direction. Figure 8 The swinging mode of the spray gun 103 and the movable frame 101 during the counterclockwise rotation of the second bevel gear 140 is shown. With the rotation of the second bevel gear 140, the slide bar 141 slides along the sliding groove 143, and the distance between the center of the second bevel gear 140 and the sliding groove 143 changes, so that the movable frame 101 swings relative to the fixed frame 102.

[0070] In other embodiments not shown, if the second motion is the linear motion, the slide bar 141 can be replaced by a third gear and a third rack (not shown). For example, the third gear is coaxially arranged with the second bevel gear 140, and the third rack extends in the left-right direction and is fixed with the fixed frame 102. When the second input wheel 127 rotates, the third gear rotates relative to the third rack through the transmission of the first bevel gear 126 and the second bevel gear 140, so that the movable frame 101 moves left and right relative to the fixed frame 102.
