In the present embodiment, the sliding direction of the sliding seat 200 along the base 100 is a front-back direction, and the moving direction of the movable platen 510 relative to the fixed platen 520 is a left-right direction. In this embodiment, the base 100, the sliding seat 200, the bidirectional cam 300 and the locking member 400 are all symmetrical structures, the symmetry axes are overlapped on a straight line, the locking member 400 is also called a compressing structure, and the locking structure and the bidirectional cam 300 together form a locking structure for locking and unlocking the angle clamp 1000.

With continued reference to fig. 3-4, the front end of the base 100 is provided with two vertical clamping plates 110 on both sides thereof, and the clamping plates 110 may be integrally formed with the base or may be separately formed and assembled together. The two clamping plates 110 are symmetrically arranged, and the pressing surfaces of the two clamping plates 110 are perpendicular to the upper surface of the base 100. The pressing surfaces of the two clamping plates 110 in this embodiment are both 90 degrees, that is, the bi-directional cam angle clamp 1000 in this embodiment can be used for fixing two frames (not shown) of 90 degrees. The pressing surfaces (not numbered) of the two clamping plates 110 can be set at other angles according to actual needs. The middle position of the base 100 has a center groove 120 provided in the sliding direction. Also provided on the base 100 are slide rails 140 disposed at opposite sides of the central groove 120 and disposed along the sliding direction. As shown in fig. 2, the bottom surface of the base 100 has a base locking portion, which in this embodiment is two base teeth 130 symmetrically disposed on both sides of the central slot 120.

The pressing table 500 is positioned on the base 100 and is movable along a sliding direction on the base 100 along with the sliding seat 200. The invention focuses on: the press table 500 is of a split type design, and comprises a fixed press table 520 and a movable press table 510, wherein the movable press table 510 can translate towards the left and right directions along two sides relative to the fixed press table 520, and then the gap between the press table 500 and the two clamping plates 110 is adjusted, so that the applicability of the press table 500 is increased, and the problem that the distribution of the pressing force is not suitable because the sizes and the thicknesses of the left frame and the right frame are different is solved. Specifically, the movable platen 510 includes two pressing surfaces 511 and an inclined surface 512, the two pressing surfaces 511 are connected to each other at one end near the clamping plate 110, the inclined surface 512 is connected to the other end of the two pressing surfaces 511, the two pressing surfaces 511 and the inclined surface 512 are the outer side surfaces of the movable platen 510 and are flat rectangular surfaces, and they together enclose the movable platen 510 forming a triangular structure. The two pressing surfaces 511 respectively cooperate with the pressing surfaces of the two clamping plates 110 to fix the frame (not shown), and the fixed platen 520 faces the inclined surface 512. The movable platen 510 includes an upper surface perpendicular to the pressing surface 511 and the inclined surface 512, the upper surface is provided with a groove 513 with an open side at the junction with the inclined surface 512, which is a second clamping portion, and a first clamping portion 521 extends from the upper edge of the upper surface of the fixed platen 520 toward the groove 513, and the first clamping portion 521 is fixed in the groove 513 and can slide in the groove 513. The recess 513 has a step 514, the width of the first clamping portion 521 in the left-right direction is smaller than the widths of the recess 513 and the step 514, the first clamping portion 521 is clamped in the step 514 in the front-back direction and the up-down direction, and the first clamping portion 521 is slidable in the recess 513 in the left-right direction. In the present preferred embodiment, the first clamping portion 521 and the groove 513 are in a form of a clamping groove, and in other embodiments, the clamping method is not limited to this clamping method, and one of the two is provided with a sliding space, and the other one is provided with a relative sliding structure to allow the fixed platen 520 and the movable platen 510 to slide in a lateral direction relative to each other, so as to adjust the position of the relative clamping plate 110 in the lateral direction.

When the fixed platen 520 slides in the front-rear direction, the movement of the upper and lower ends in the front-rear direction is inconsistent, so that the fixed platen 520 is inclined to cause the bottom to tilt up, and therefore, a positioning structure for preventing tilting is required to be arranged at the bottom of the fixed platen 520. Specifically, a cylinder 523 is disposed below the fixed platen 520, and a cylinder groove 250 is disposed at a position of the slide base 200 corresponding to the cylinder 523 to receive and position the cylinder 523. The central axis of the cylinder 523 is parallel to the sliding direction, and one side of the circumferential side of the cylinder 523 is extended to form a connection portion 524 to connect the fixed platen 520. The sliding seat 200 is provided with a cylindrical groove 250 having a parallel central axis corresponding to the cylindrical body 523 to receive and position the cylindrical body 523, and a slot 251 is formed at one side of the inner circumferential side of the cylindrical groove 250 to allow the connection portion 524 to protrude. In the preferred embodiment of the present invention, the cylindrical groove 250 and the cylindrical body 523 are both cylindrical, and in other embodiments, the outer contours of both may be appropriately deformed. When mounting, the cylinder 523 can be inserted into the cylinder groove 250 in the sliding direction, and after mounting, the movement of the fixed platen 520 in the vertical direction perpendicular to the base 100 can be prevented, thereby preventing the bottom of the fixed platen 520 from being lifted during sliding.

The slide base 200 includes a frame-shaped base 201, two parallel spaced fixing plates 202 provided at both left and right sides of the frame-shaped base 201, and a connection plate 203 connected to the top sides of the two fixing plates 202. Each fixing plate 202 is provided with a long round hole 210 for the two ends of the rotation shaft 600 of the locking member 400 to pass through, so as to support and guide the locking member 400 in the up-down direction. The fixing plate 202 is recessed outside the oblong hole 210 to form a rectangular limit groove 220. The fixed platen 520 extends toward the sliding seat 200 on both sides thereof, and the sliding boss 522 is accommodated in and limited by the limiting groove 220, so that the sliding seat 200 and the fixed platen 520 can be locked in the sliding direction, and the sliding boss 522 can partially shield the rotation shaft 600 in the oblong hole 210, so as to prevent the rotation shaft from falling off due to axial movement. The guide structures 240 are disposed above two sidewalls of the sliding seat 200, and the guide structures 240 are specifically a section of arc-shaped protrusion on the inner side surface of the sliding seat 200.

The bi-directional cam 300 includes two parallel spaced cam portions 301, and an operation handle 302 connected to the same side of the two cam portions, and a receiving groove 303 is formed between the two cam portions 301. The bidirectional cam 300 is perforated in the left-right direction to allow the rotation shaft 600 to pass through the two cam portions 301. The two cam portions 301 are pivoted to the sliding base 200 through a rotation shaft 600, and rotate around the rotation shaft 600 relative to the sliding base 200. The rotation surfaces 310 of the cam portions 301 rotate on the base 100. The surface of revolution 310 of the bi-directional cam 300 has a locking end 320 and an unlocking end 330 that transition smoothly therebetween. The distance from the locking end 320 to the center of rotation of the bi-directional cam 300 is greater than the distance from the unlocking end 330 to the center of rotation of the bi-directional cam 300. The bi-directional cam 300 can provide a locking state and an unlocking state, when in the locking state, the bi-directional cam 300 is rotated to enable the locking end 320 to be parallel and cling to the base 100, the unlocking end 330 is parallel and props against the fixed pressing table 520, and the locking end 320 is far away from the rotating shaft 600, so that the rotating shaft 600 moves upwards in the oblong hole 210 to drive the locking member 400 to move upwards to be meshed with the base teeth 130, at this time, the positions of the sliding seat 200, the bi-directional cam 300 and the pressing table 500 are relatively fixed, and the pressing table 500 is pressed against the clamping plate 110 by the locking member 400; in the unlocking state, the bidirectional cam 300 is rotated to enable the unlocking end 330 to be parallel to and cling to the base 100, and the rotating shaft 600 moves downwards in the oblong hole 210 due to the fact that the unlocking end is closer to the rotating shaft 600 than the locking end 320, the locking piece 400 sinks down along with the oblong hole, is disengaged from the base teeth 130 of the base 100 and can slide along the base 100 relatively, and at the moment, the positions of the sliding seat 200, the locking piece 400 and the pressing table 500 in the sliding direction relative to the base 100 can be adjusted.

The edge of the protruding part of the bidirectional cam 300 is provided with the guided convex point 350, when the bidirectional cam 300 is operated to rotate, the guided convex point 350 can drive the bidirectional cam 300 to sink under the downward pressure of the guiding structure 240, and further can drive the locking piece 400 to press down, so that the locking piece 400 is allowed to slide back and forth, and therefore, the guiding structure 240 of the sliding seat 200 can effectively guide the pressing track of the bidirectional cam 300, and further, the bidirectional cam 300 is prevented from automatically pressing down to cause failure.

The locking member 400 has an inverted T shape and includes a vertical portion 401 and a plate-shaped horizontal portion 402. The upper end of the vertical portion 401 is provided with a rotation hole through which the rotation shaft 600 is rotatably pivoted with the cam portion 301 of the bidirectional cam 300 and the slide base 200 in order from inside to outside. The vertical portion 401 of the locking member 400 passes through the central groove 120 of the base 100 and is inserted into the receiving groove 303 of the bi-directional cam 300. Locking teeth 410 are symmetrically disposed on both sides of the bottom of the horizontal portion 402. The locking teeth 410 are engaged with the base teeth 130 of the base 100, and the locking member 400 is locked with the base 100 when the two are engaged.

In the use process of the angle clamp 1000, because the locking member 400 is fixed by rotating relative to the rotation shaft 600, the horizontal portion 402 is easy to incline relative to the horizontal plane in the sliding direction, so that the clamping between the horizontal portion 402 and the base teeth 130 of the base 100 is not stable enough and inaccurate, and therefore the inclination of the locking member 400 in the sliding direction needs to be limited, and therefore, a limiting structure in the sliding direction needs to be provided. Specifically, the frame base 201 of the sliding seat 200 is provided with a limit fixture block 260 behind the vertical portion 401, that is, on the front edge of the frame base 201, and the limit fixture block 260 abuts against the rear surface of the vertical portion 401; meanwhile, the bi-directional cam 300 is provided with a limiting wall 340 in front of the vertical portion 401, and the limiting wall 340 faces the front surface of the vertical portion 401 of the locker 400, so that both front and rear sides of the vertical portion 401 of the locker 400 are limited by the sliding seat 200 and the bi-directional cam 300 without tilting regardless of how the bi-directional cam 300 rotates with respect to the rotation shaft 600.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples merely illustrate embodiments of the invention and are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
