Description

Technical Field

[0001] The invention relates to a clamp tool and a use method thereof, and in particular to a clamp tool for fixing an aluminum template and a method for fixing the aluminum template using the clamp tool. Background Art

[0002] The construction of reinforced concrete (RC) buildings requires the assembly and fixing of formworks in advance for the subsequent concrete pouring. When assembling the formworks, adjacent formworks must be firmly fixed to each other to avoid accidental collapse of the formworks during the concrete pouring operation. Therefore, the quality and speed of the formwork fixing operation affect the quality and construction safety of the overall building structure.

[0003] Aluminum formwork is gradually being adopted by the industry due to its light weight, flat surface and reusability. The conventional method of fixing adjacent aluminum formworks is for the operator to use a hammer, a wooden mallet or a champagne hammer to knock the clamping piece into the fixing piece used to fix the adjacent formworks, so as to clamp and fix the two adjacent formworks. However, the disadvantage of this method is that the use of hand tools to knock will generate a lot of noise, such as the metal noise caused by the hand tool touching the aluminum formwork when knocking. Such noise pollution not only affects the operator, but also may cause the noise of formwork construction work to disturb neighbors, or may violate the relevant engineering noise control laws.

[0004] In addition, the hammer surface of conventional hammers (especially wooden hammers or champagne hammers) is often easily damaged due to repeated knocking, and the hammering tool must be replaced, which makes it impossible for the operator to maintain a relatively constant quality of the template fixing operation, or even temporarily interrupt the construction. Furthermore, since the aluminum template structure usually has ribs as reinforcements, it is easy to interfere with the knocking operation when fixing adjacent templates, making it difficult for the operator to accurately and effectively knock on the clamping parts, affecting the operation speed.

[0005] In view of the shortcomings of the conventional method of fixing the assembled formwork by hammering, how to provide a tool for fixing adjacent formworks that is easy for the operator to use and has a long service life so as to quickly perform formwork fixing operations has long been desired by the industry.

[0034] Figure 1 The preferred embodiment of the clamping tool of the present invention for fixing adjacent aluminum templates is shown. Figure 1 As shown, the clamp tool 1 includes a first clamp handle 10, a second clamp handle 20, a first clamp portion 30 and a second clamp portion 40. The first clamp handle 10 includes a first connecting end 11, the first connecting end 11 includes an inner portion 12 and an outer portion 13 opposite to the inner portion 12. The second clamp handle 20 includes a second connecting end 21, the second connecting end 21 includes an inner portion 22 and an outer portion 23 opposite to the inner portion 22, and the inner portion 22 of the second connecting end 21 of the second clamp handle 20 and the inner portion 12 of the first connecting end 11 of the first clamp handle 10 are pivotally connected to each other by a pivot element A1.

[0035] In addition, the first clamping part 30 of the clamping tool 1 includes a third connecting end 31, the third connecting end 31 includes an inner portion 32 and an outer portion 33 opposite to the inner portion 32, wherein the outer portion 33 of the first clamping part 30 is pivotally connected to the outer portion 13 of the first connecting end 11 of the first clamp handle 10 by a pivot element A2. The second clamping part 40 of the clamping tool includes a fourth connecting end 41, the fourth connecting end includes an inner portion 42 and an outer portion 43 opposite to the inner portion 42, wherein the outer portion 43 of the second clamping part 40 is pivotally connected to the outer portion 23 of the second connecting end 21 of the second clamp handle 20 by a pivot element A3. In addition, the inner portion 32 of the third connecting end 31 of the first clamping part 30 of the clamping tool 1 is pivotally connected to the inner portion 42 of the fourth connecting end 41 of the second clamping part 40 by a pivot element A4.

[0036] The pivotal structure of the first pliers handle 10, the second pliers handle 20, the first clamping part 30 and the second clamping part 40 of the clamping tool 1 is designed so that when the first pliers handle 10 pivots toward the first rotation direction R1 and the second pliers handle 20 pivots toward the second rotation direction R2 opposite to the first rotation direction R1, so that the first pliers handle 10 and the second pliers handle 20 move away from each other, the second clamping part 40 pivots toward the first rotation direction R1 and the first clamping part 30 pivots toward the second rotation direction R2 opposite to the first rotation direction R1, so that the first clamping part 30 and the second clamping part 40 move away from each other. Figure 1 In the preferred embodiment of the pliers tool shown, the first connection end 11 of the first pliers handle 10 is configured to abut against the configured fourth connection end 41 of the second jaw portion 40. Similarly, the second connection end 21 of the second pliers handle 20 is configured to abut against the configured third connection end 31 of the first jaw portion 30.

[0037] Figure 2 exhibit Figure 1 A partial enlarged view of the clamp tool in Figure 1. Figure 2 and Figure 3 As shown, the first clamping part 30 of the clamping tool 1 forms a configuration such as a cylindrical ring 341 relative to the free end 34 of the third connecting end 31, and a through hole 342 is formed in the center of the cylindrical ring 341, and the push component 50 is inserted into the through hole 342 (see Figure 3 ).also, Figure 2 The second clamping part 40 of the clamping tool 1 further has an abutment member 60 at the free end 44 relative to the fourth connecting end 41. Figure 2 In the illustrated embodiment, the abutting member 60 extends from the free end 44 of the fourth connecting end 41 in the length direction of the clamp tool, and has an open groove 61 formed along the length direction of the abutting member 60 , and an abutting surface 62 is formed on the top of the abutting member.

[0038] Figure 3 The exploded structure diagram of the pressing member 50 and the cylindrical ring 341 of the first clamp handle 30 is shown. Figure 3 As shown, the push component 50 may include a push element 51 and a locking element 52. The push element 51 (for example, a bolt or a pin) has a push body 511 and a column portion 512 protruding from the push body 511 through the through hole 342 of the column ring 341. The push element 51 is locked on the column ring 50 via a locking member 52 (for example, a nut or a fastener). The push body 511 of the push element 51 may be cylindrical or drum-shaped, and has a downward surface 513 as a push surface.

[0039] In another embodiment, Figure 2The push component 50 and the abutting component 60 of the clamp tool 1 shown can also be arranged in the opposite manner, that is, the free end 44 of the second clamp part 40 forms a cylindrical ring, and the push component 50 is arranged in the cylindrical ring, and the abutting component 60 is arranged on the free end 34 of the first clamp part 30.

[0040] Figure 4 Shows adjacent assembled aluminum formwork structures to be fixed. Figure 4 As shown, when assembling the formwork 7 at the construction site, a plurality of formworks 7 are arranged adjacent to each other in sequence. Figure 4 The aluminum template 7 shown has side panels 72 protruding roughly vertically along the surface of the aluminum template 7 on both sides, and has at least one or more perforations 73 corresponding to the height position at a specific height of the side panel 72. The side panel 72 has a side surface 74 and a front surface 75.

[0041] Figure 4 Also shown is a clamping rod 8 and a clamping pin 9 for fixing two adjacent aluminum templates 7, and the structure of the clamping rod 8 and the clamping pin 9 is shown in Figure 5 In. Figure 5 As shown, the clamping rod 8 has a head 81, a tapered rod 82 extending from one side of the head 81, and a pore 83 penetrating one end of the rod 82 in the radial direction of the clamping rod. The diameter of the head 81 of the clamping rod 8 is larger than the diameter of the base of the tapered rod 82 extending from the head 81, so an annular surface 811 is formed between the periphery of the head 81 and the base of the tapered rod 82. Figure 5 In the structure shown, the clamping pin 9 has a trapezoidal shape, the side edge 91 of the clamping pin 9 is a vertical surface, and the other side edge 92 presents an inclined surface that shrinks from top to bottom, and the clamping pin 9 is configured to provide its narrower lower end for first inserting into the hole 83 of the tapered rod portion 82 of the clamping rod 8, so that the clamping pin 9 is finally pressed into and fully fills the hole 83 of the clamping rod 8.

[0042] Figure 4 as well as Figures 6 to 10 A schematic diagram showing the use of a clamp tool 1 to fix adjacent assembled aluminum templates 7. Figure 4 As shown, before fixing two adjacent aluminum templates 7, the adjacent aluminum templates 7 are assembled first, and the plurality of perforations 73 on the adjacent side plates 72 of the adjacent aluminum templates 7 are aligned with each other. Figure 6 As shown, the clamping rod 8 is inserted into the through hole 73 of one of the adjacent aluminum templates 7 and is passed out from the corresponding through hole 73 of the other adjacent aluminum template 7, so that the head 81 of the clamping rod 8 abuts against the side plate of the left aluminum template 7, and a part of the rod 82 of the clamping rod 8 and the hole 83 are exposed to the side of the side plate of the other adjacent right template 7. Subsequently, the tightening pin 9 is inserted into the hole 83 of the clamping rod 8, as shown in FIG. Figure 7Then, the clamping pin 9 is pressed into the hole 83 of the clamping rod 8 by a tool and fully fills the hole 83, so that the side edge 91 of the clamping pin 9 is pressed against the side surface 74 of the side plate portion 72 of the other aluminum template 7, and the side edge 92 of the clamping pin 9 is pressed against the side wall in the hole 83 of the rod portion 82 of the clamping rod 8. At this time, the annular surface 811 of the head 81 of the clamping rod 8 is pressed against the side surface 74 of the side plate portion 72 of the left aluminum template 7, so that the two adjacent aluminum templates 7 are fixed to each other.

[0043] Figure 8 and Fig. 9 The clamp tool 1 is used to press the clamp pin 9 into the hole 83 of the filling clamp rod 8, and the clamp pin 9 is pressed against the aluminum template 7 to fix the adjacent aluminum templates 7 to each other. Figure 7 As shown, first insert the tightening pin 9 into the hole 83 of the clamping rod 8, and then Figure 8 As shown, the first clamp handle 10 and the second clamp handle 20 of the clamp tool 1 are pivoted in the counterclockwise direction R2 and the clockwise direction R1 respectively, so that the first clamp part 30 and the second clamp part 40 are separated from each other and in an open state. Then, the portion of the clamp pin 9 located below the clamp rod 8 is accommodated in the open groove 61 of the abutting component 60 of the second clamp part 40 of the clamp tool 1, and the abutting surface 62 of the abutting component 60 is pressed against the surface below the clamp rod 8. Then, the first clamp handle 10 and the second clamp handle 20 are clamped, so that the pressing surface 513 of the pressing component 50 located at the end of the first clamp part 30 presses against the upper surface of the clamp pin 9. Then, as shown in FIG. Fig. 9 As shown, the first clamp handle 10 and the second clamp handle 20 are clamped, so that the first clamp handle 10 and the second clamp handle 20 are pivoted in the clockwise rotation direction R1 and the counterclockwise rotation direction R2 respectively. At this time, since the abutting surface 62 of the abutting component 60 at the end of the second clamp part 40 abuts against the surface below the clamping rod 8, the second clamp part 40 will be stopped by the clamping rod 8 and cannot continue to pivot in the clockwise rotation direction R1, while the first clamp handle 30 will continue to pivot in the counterclockwise rotation direction R2, pushing the pushing surface 513 of the pushing component 50, and pressing the clamping pin 9 further downward into the hole 83 of the clamping rod 8, until the clamping pin 9 is fully filled and clamped in the hole 83 of the clamping rod 8, and basically cannot be inserted further downward. At this point, the side edge 91 of the clamping pin 9 is forced to press against the side surface 74 of the side plate portion 72 of the right aluminum template 7, thereby fixing the adjacent left and right aluminum templates 7 to each other. Fig.10 shown.

[0044] On the contrary, when the concrete pouring operation is completed and the aluminum formwork 7 is to be removed, the clamping rod 8 and the locking pin 9 must be removed first. Figure 11 to Figure 13 The process of using the clamp tool 1 to remove the clamping rod 8 and the locking pin 9 from two adjacent fixed templates 7 is shown. Fig.11As shown, after the operator opens the clamp tool 1, the part of the clamp pin 9 located above the clamp rod 8 is accommodated in the open groove 61 of the abutting component 60 of the second clamp part 40 of the clamp tool 1, and the abutting surface 62 of the abutting component 60 is pressed against the upper surface of the clamp rod 8, and then the operator gently holds the first clamp handle 10 and the second clamp handle 20 so that the pressing surface 513 of the pressing component 50 located at the end of the first clamp part 30 is pressed against the lower surface of the clamp pin 9. Then, as shown in FIG. Fig.12 As shown, start clamping the first clamp handle 10 and the second clamp handle 20, so that the first clamp handle 10 and the second clamp handle 20 pivot in the counterclockwise direction R2 and the clockwise direction R1, respectively. Since the abutting surface 62 of the abutting component 60 at the end of the second clamp portion 40 abuts against the upper surface of the clamping rod 8, the second clamp portion 40 will be stopped by the upper surface of the clamping rod 8 and cannot pivot in the counterclockwise direction R2, while the first clamp portion 30 will continue to pivot in the clockwise rotation direction R1, so that the pressing surface 513 of the pressing component 50 moves forward and pushes the clamping pin 9 upward from the hole 83 of the clamping rod 8 until the clamping pin 9 moves upward from the clamping state in the hole 83 of the clamping rod 8 and presents a released loose state. At this point, the clamp tool 1 can be removed, and the clamping pin 9 can be removed from the hole 83 of the clamping rod 8 manually or with other tools (such as Fig.13 As shown), the fixing rod 8 is then pulled out from the corresponding through holes 73 of the two adjacent aluminum templates 7, and then the two adjacent aluminum templates 7 that are assembled are removed separately.

[0045] Fig.14 A clamping tool 1' for fixing adjacent aluminum templates according to another preferred embodiment of the present invention is shown. Fig.14 As shown, the clamp tool 1' comprises a hydraulic mechanism 10', a support member 20', a bracket member 30', a connecting rod assembly 40' and a clamping member 50'. It should be noted that the supporting member 20', the bracket member 30', the connecting rod assembly 40' and the clamping member 50' of the clamp tool 1' can be designed and constructed to form an assembly structure 60', and then combined with the hydraulic mechanism 10' in a detachable manner to form a Fig.14 The structure of the clamp tool 1' is shown.

[0046] As mentioned above, the hydraulic mechanism 10' includes a main body 11', a hydraulic push rod 12' and a handle portion 13' connected to the main body 11'. The main body 11' is provided with a switch 111', which is used to operate the hydraulic pressure in the main body 11' of the hydraulic mechanism 10' of the clamp tool 1', so that the hydraulic push rod 12' of the hydraulic mechanism 10' can be extended and retracted between the ejection position and the retracted position along the axial direction of the main body 11'. In other words, the axial direction is also the extension and retraction direction of the hydraulic push rod. The support component 20' has a main support platform 21' and an abutment portion 22' extending from one side of the main support platform 21' along the extension and retraction direction of the hydraulic push rod 12'. As shown Fig.14 As shown, the main support platform 21' and the abutment portion 22' jointly form a receiving gap 23' therein. A bracket component 30' is fixedly arranged on the main support platform 21' of the support component 20'. The structure of the bracket component 30' may include a pair of bracket plates 31' fixedly arranged on the main support platform 21' in parallel with each other along the extension and retraction direction of the hydraulic jack. An accommodating space 32' may be defined between the pair of bracket plates 31'. The accommodating space 32' may be used to accommodate and install a connecting rod assembly 40'. The first side of the connecting rod assembly 40' is connected to the hydraulic jack 12', and the second side of the connecting rod assembly 40' is connected to the clamping component 50' located above the abutment portion 22' of the support component 20'.

[0047] exist Fig.14 In the illustrated structure, the connecting rod assembly 40' includes a first connecting rod 41' and a second connecting rod 42', wherein the first connecting rod 41' is generally L-shaped and is pivoted on two bracket plates 31' at the turning point of the L-shaped structure, so that the first connecting rod 41' is located in the accommodating space 32'. In addition, one end of the first connecting rod 41' is connected or joined to the hydraulic jack 12', and the other end is pivoted to the clamping component 50'. The second connecting rod 42' of the connecting rod assembly 40' is located above the first connecting rod 41', and one end of the second connecting rod 42' is pivoted on the bracket plate 31' and located in the accommodating space 32', and the other end of the second connecting rod 42' is pivoted to the clamping component 50'. The clamping component 50' may also be roughly L-shaped, and the other end of the second connecting rod 42' is roughly pivoted at the middle turning point of the L-shaped structure of the clamping component 50', wherein the other end of the first connecting rod 41' is pivoted at the position P1 of the clamping component 50', and is located below the position P2 where the second connecting rod 42' is pivoted at the clamping component 50'.

[0048] exist Fig.14 In the clamp tool 1' shown, when the operator operates the switch 111' of the hydraulic mechanism 10' to extend the hydraulic push rod 12' to be in the ejection position, since one end of the first connecting rod 41' is connected to the hydraulic push rod 12' and the other end is pivoted on the clamping component 50' (at P1), the movement of the hydraulic push rod 12' will drive the first connecting rod 41' to rotate counterclockwise around the axis of the pivot point B1 between the first connecting rod 41' and the bracket plate 31', thereby driving the clamping component 50' to operate. The second connecting rod 42' is pivotally mounted on one end (P2) of the clamping component 50'. The first connecting rod 41' drives the clamping component 50' to move, and the clamping component 50' will also drive the second connecting rod 42', causing the second connecting rod 42' to rotate counterclockwise around the axis B2 of the pivot point between the second connecting rod 42' and the bracket plate 31', and finally causing the free end 51' of the clamping component 50' to move in a direction away from the abutment portion 22' of the support component 20'.

[0049] On the contrary, when the operator operates the switch 111' of the hydraulic mechanism 10 to retract the hydraulic push rod 12' from the ejection position to the retracted position, the movement of the hydraulic push rod 12' will drive the first connecting rod 41' to rotate clockwise around the axis of the pivot point B1 between the first connecting rod 41' and the bracket plate 31', thereby driving the clamping component 50' to operate. In addition, the first connecting rod 41' drives the movement of the clamping component 50', which will cause the clamping component 50' to drive the second connecting rod 42', so that the second connecting rod 42' rotates clockwise around the axis of the pivot point B2 between the second connecting rod 42' and the bracket plate 31', and finally causes the free end 51' of the clamping component 50' to move toward the direction close to the abutment portion 22' of the support component 20'.

[0050] Fig.15 and Fig.16 The clamp tool 1' is used to press the clamp pin 9 into the hole 83 of the filling clamp rod 8 to clamp the clamp pin 9 against the aluminum template 7 to fix the adjacent aluminum templates 7 to each other. Figure 7 As shown, the tightening pin 9 is inserted into the hole 83 of the clamping rod 8, and then according to Fig.15 As shown, the clamp tool 1' is operated so that the hydraulic push rod 12' of the hydraulic mechanism 10' of the clamp tool 1' is located at the ejection position, and the free end 51' of the clamping component 50' is located away from the abutment 22', so that the opening between the free end 51' and the abutment 22' reaches the maximum.

[0051] Then, the operator places the front surface of the main support platform 21' of the support component 20' of the clamp tool 1' directly against the front surface 75 of the side plate portion 72 of the adjacent aluminum template 7 that has been assembled, and makes the upper surface of the abutting portion 22' of the support component 20' abut against the surface below the clamping rod 8, thereby making the side plate portion 72 of the adjacent aluminum template 7 and the clamping pin 9 both located in the receiving notch 23' of the clamp tool 1'. Fig.15 As shown, the arm portion A of the L-shaped structure including the free end 51 ′ of the clamping member 50 ′ of the clamping tool 1 ′ is located above the upper surface of the clamping pin 9 .

[0052] Afterwards, if Fig.16As shown, the operator operates the switch 111' of the clamp tool 1', so that the hydraulic push rod 12' moves from the ejection position to the retracted position, thereby driving the arm portion of the clamping component 50' including the free end 51' to move toward the direction of the abutment portion 22' close to the support component 20' (i.e., move downward). After the free end 51' of the clamping component touches the upper surface of the clamping pin 9, the clamping pin 9 begins to be pressed downward into the hole 83 of the clamping rod 8 until the clamping pin 9 is fully filled and forced to be clamped in the hole 83 of the clamping rod 8 and is generally unable to be inserted further downward. The operator has completed the operation and removes the clamp tool 1'. At this time, the side edge 91 of the clamping pin 9 is pressed against the side surface 74 of the side plate portion 72 of the aluminum template 7, thereby fixing the adjacent aluminum templates 7 to each other (such as Fig.10 shown).

[0053] Similarly, when the concrete pouring operation is completed and all the assembled and fixed aluminum formworks 7 are to be removed, the clamping rods 8 and the locking pins 9 must be removed first. Fig.17 and Fig.18 The process of removing the clamping rod 8 and the clamping pin 9 from two adjacent templates 7 with a clamp tool 1' is shown to facilitate the subsequent removal of the aluminum template 7. Since the clamping pin 9 is located on one side of one of the two adjacent aluminum templates 7, the operator can remove the clamping rod 8 and the clamping pin 9 from the adjacent template 7. Fig.14 The assembly structure 60' (including the support member 20', the bracket member 30', the connecting rod assembly 40' and the clamping member 50') of the clamp tool 1' shown in the figure is removed from the clamp tool 1' and replaced by another assembly structure 60", wherein the components of the assembly structure 60" are basically the same as the components of the assembly structure 60' (including the support member 20', the bracket member 30', the connecting rod assembly 40' and the clamping member 50'), but are in a left-right mirror image or symmetrical relationship along the axis of the handle portion 13' (such as Fig.17 The clamp tool 1' shown in the figure includes a support member 20", a bracket member 30", a connecting rod assembly 40" and an assembly structure 60" of a clamping member 50". Fig.14 The assembly structure 60' shown in the figure is in a left-right mirror symmetric relationship along the axis of the handle portion 13') to facilitate the removal of all the clamping rods 8 and the tightening pins 9.

[0054] As described above, the operator replaces the assembly structure 60' of the clamp tool 1' with Fig.17After the assembly structure 60" is shown, the operator operates the hydraulic switch 111' of the hydraulic mechanism 10' to place the hydraulic push rod 12' in the ejection position, thereby driving the first connecting rod 41" and the second connecting rod 42" pivotally connected between the two bracket plates 31" of the bracket component 30", so that the free end 51" of the clamping component 50" connected to the first connecting rod 41" and the second connecting rod 42" moves to a position away from the abutment portion 22", thereby maximizing the opening between the free end 51" and the abutment portion 22".

[0055] Then, the operator turns the clamp tool 1' over 180 degrees and uses it, and directly presses the front surface B of the main support platform 21" of the support component 20" of the clamp tool 1' against the two front surfaces 75 of the side plate portion 72 of the adjacent aluminum template 7. At this time, the upper surface of the abutting portion 22" of the support component 20" presses against the surface above the clamping rod 8, so that the side plate portion 72 of the adjacent aluminum template 7 and the clamping pin 9 are both located in the receiving notch 23" of the clamp tool 1'. At this time, Fig.17 As shown, the arm portion A of the L-shaped structure of the clamping member 50 ″ of the clamping tool 1 ′ including the free end 51 ″ is located below the lower surface of the clamping pin 9 .

[0056] Afterwards, if Fig.18 As shown, the operator operates the hydraulic switch 111' of the clamp tool 1', so that the hydraulic push rod 12' moves from the ejection position to the retracted position, thereby driving the arm portion of the clamping component 50" including the free end 51" to move toward the direction of the abutment portion 22" close to the support component 20" (in the direction of the hydraulic switch 111' of the clamp tool 1'). Fig.18 At this time, the free end 51" of the clamping member 50" touches the lower surface of the clamping pin 9 and starts to push the clamping pin 9 upward from the hole 83 of the clamping rod 8, thereby the clamping pin 9 moves upward from the clamping state fully filled in the hole 83 of the clamping rod 8 to a released state. At this point, the clamping tool 1' can be removed, and the clamping pin 9 can be removed from the hole 83 of the clamping rod 8 by hand or other means (such as Fig.19 Then the operator pulls out the clamping rod 8 from the corresponding through holes 73 of the two adjacent aluminum templates 7, and removes the assembled adjacent aluminum templates 7 respectively.

[0057] In summary, by using the clamp tool 1 or clamp tool 1' proposed by the present invention, when assembling aluminum formwork 7 or removing the assembled formwork 7 at a construction site or a precasting factory, it can replace the conventional hammer, wooden hammer, or champagne hammer, etc., which are used as a knocking hand tool for fixing or loosening the clamp rod and the clamp pin used for assembling adjacent aluminum formworks. Therefore, when the knocking method is no longer used, the noise caused by knocking to fix or remove the clamp rod and the clamp pin can be effectively reduced. Furthermore, when the clamp tool 1 or clamp tool 1' proposed by the present invention is used to fix the clamp rod and the clamp pin, for the operator, compared with the hammering method, a more uniform fixing force of the clamp pin on the clamp rod can be achieved, and the situation of excessive tightening can be reduced. Therefore, when removing the clamp rod and the clamp pin, it is also more labor-saving and quick. Furthermore, in terms of construction convenience, the clamp tool 1 or clamp tool 1' proposed in the present invention can be used to easily and quickly fix or remove the clamping rod and the locking pin at one time, which can improve the working efficiency compared with the conventional hammering method. The conventional hammering method easily causes the hammer surface of the iron hammer, wooden hammer, or champagne hammer to be worn and the working life of the hammer is reduced. When the clamp tool 1 or clamp tool 1' proposed in the present invention is used, the disadvantage no longer exists.

[0058] Although the present invention has been described in terms of its preferred embodiments, it will be apparent to those skilled in the art that various modifications may be made to the described embodiments without departing from the scope of the application as defined by the appended claims.
