At the same time, under the joint action of the two guide rods 43, the clamp block 3 slides horizontally along its own width direction, thereby driving the guide to slide synchronously, which helps to make a preliminary adjustment to the position of the guide clamp on the mounting seat 1.

[0039] Reference Figure 4The block 3 is hollow inside, and a displacement driving mechanism is arranged inside the block 3. The displacement driving mechanism includes a driving screw 7, which is rotatably installed in the block 3 along the length direction of the block 3, and one end of the driving screw 7 extends out of the block 3. The displacement driving mechanism also includes a movable block 8 and multiple groups of top support components 11. The movable block 8 is located above the driving screw 7 and a driving half nut 9 is fixedly embedded on the bottom surface of the movable block 8. The multiple groups of top support components 11 are symmetrically arranged at the bottom of the movable block 8 and on both sides of the driving half nut 9. A push plate 10 is fixedly installed on the top surface of the movable block 8, and the top end of the push plate 10 extends out of the block 3.

[0040] Reference Figure 4 and Figure 5 Each group of supporting components 11 includes a first sleeve 111, a second sleeve 112, a movable rod 113 and a supporting spring 114. The first sleeve 111 is fixedly mounted on the bottom surface of the movable block 8.

[0041] Reference Figure 4 and Figure 5 The supporting spring 114 drives the first sleeve 111 to elastically support the movable block 8 under the action of its own elastic force, so that there is a gap between the driving half nut 9 and the driving screw 7 in the vertical direction, and the driving half nut 9 and the driving screw 7 are in a non-connected state.

[0042] Reference Figure 4 and Figure 6 A pressing assembly 12 is also provided inside the block 3. The pressing assembly 12 includes a pressing plate 121, a connecting rod 122, a connecting plate 123 and a plug-in protrusion 124. The pressing plate 121 can be lifted and placed on the top surface of the movable block 8. A plurality of telescopic rods are arranged at intervals along the length direction of the pressing plate 121. The top of each telescopic rod is fixedly connected to the inner top wall of the block 3. One end of the connecting rod 122 is horizontally slidably plugged into the side wall of the pressing plate 121 in the length direction. The block 3 is provided with a first waist hole 14. The other end of the connecting rod 122 passes through the first waist hole 14 and extends out of the block 3. The connecting plate 123 is fixedly mounted on the end of the connecting rod 122 located outside the block 3. The plug-in protrusion 124 is fixedly mounted on the side of the connecting plate 123 facing the block 3. A plug-in hole 15 is provided on the side wall of the block 3 at a position aligned with the plug-in protrusion 124.

[0043] Reference Figure 4 and Figure 6 The operator pushes the connecting plate 123 downward so that the plug-in protrusion 124 is inserted into the corresponding socket 15, and the lower pressure plate 121 is driven to move downward synchronously through the connecting rod 122, thereby pressing down the movable block 8, so that the movable block 8 drives the driving half nut 9 to move downward synchronously, and then the driving half nut 9 and the driving screw 7 are threadedly connected, that is, the driving half nut 9 and the driving screw 7 are in a threaded connection state.

[0044] Reference Figure 4 When the driving half nut 9 and the driving screw 7 are in a threaded connection state, the operator rotates the driving screw 7 to drive the driving half nut 9 and the movable block 8 to move along the length direction of the block 3, thereby driving the push plate 10 to push the guide to slide along the length direction of the block 3, which helps to further adjust the position of the guide clamp placed on the mounting seat 1.

[0045] Reference Figure 7 and Figure 8 A locking assembly 5 is also provided inside the card block 3, and the locking assembly 5 includes a connecting rod 51, a connecting block 52, a guide rod 53 and a locking plate 54. A clamping groove 18 is provided on both inner walls in the length direction of the card block 3. A clamping block 19 is slidably clamped inside the clamping groove 18. A telescopic spring 20 is fixedly installed inside the clamping groove 18 on the side of the clamping block 19 away from the card block 3. One end of the telescopic spring 20 is fixedly connected to the clamping block 19, and the other end is fixedly connected to the groove wall of the clamping groove 18. Each end of the guide rod 53 is fixedly connected to a clamping block 19, the connecting block 52 is slidably sleeved on the guide rod 53, one end of the connecting rod 51 is hinged to the connecting block 52, and the other end is hinged to the movable block 8, the locking plate 54 is fixedly installed on the connecting block 52, a clearance opening 17 is provided on the side wall of the clamping block 3, and one end of the locking plate 54 away from the connecting block 52 is inserted into the clearance opening 17, and a fixing rod 21 is fixedly installed on the inner wall of the clearance opening 17, and a second waist hole 22 is provided on the locking plate 54, and the fixing rod 21 passes through the second waist hole 22.

[0046] Reference Figure 7 and Figure 8 When the position adjustment of the guide is completed, the operator stops the pressing plate 121 from pressing down the movable block 8, and the movable block 8 is driven to move upward under the elastic force of the supporting spring 114, thereby driving the connecting block 52 to move horizontally away from the movable block 8 through the connecting rod 51 and the engaging block 19, so that the locking plate 54 extends out of the engaging block 3 through the giving opening 17, which helps to lock the position of the guide on the mounting seat 1 through the locking plate 54.

[0047] The implementation principle of the embodiment of the present application is: when installing the guide, the guide clamp is placed on the clamp block 3, and the operator rotates the adjustment screw 41 to drive the internal threaded sleeve 42 to rotate synchronously. At the same time, under the joint action of the two guide rods 43, the clamp block 3 slides horizontally along its own width direction, thereby driving the guide to slide synchronously, which helps to make a preliminary adjustment to the position of the guide clamp placed on the mounting seat 1.

[0048] The operator pushes the connecting plate 123 downward so that the plug-in protrusion 124 is inserted into the socket 15 accordingly, and drives the lower pressure plate 121 to move downward synchronously through the connecting rod 122, thereby pressing down the movable block 8, so that the movable block 8 drives the driving half nut 9 to move downward synchronously, and then the driving half nut 9 and the driving screw 7 are threadedly connected, that is, the driving half nut 9 and the driving screw 7 are in a threaded connection state.

[0049] When the driving half nut 9 and the driving screw 7 are in a threaded connection state, the operator rotates the driving screw 7 to drive the driving half nut 9 and the movable block 8 to move along the length direction of the block 3, thereby driving the push plate 10 to push the guide to slide along the length direction of the block 3, which helps to further adjust the position of the guide clamp placed on the mounting seat 1.

[0050] When the position adjustment of the guide is completed, the operator makes the lower pressure plate 121 no longer press down on the movable block 8. Under the action of the elastic force of the top support spring 114 itself, the movable block 8 is driven to move upward, thereby driving the connecting block 52 to move horizontally away from the movable block 8 through the connecting rod 51 and the locking block 19, so that the locking plate 54 extends out of the locking block 3 through the clearance opening 17, which helps to lock the position of the guide on the mounting seat 1 through the locking plate 54.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
