[0042] Reference Figures 1 to 3 A portable board processing clamp includes a folding unit 100 and a connecting component. The number of the folding units 100 is set to two, and the two folding units 100 are connected by the connecting component.

[0043] The folding unit 100 includes a fixing block, a bottom bar 120 and a corner positioning block 130 .

[0044] The number of the bottom rods 120 and the number of the corner positioning blocks 130 are both set to two, and the bottom rods 120 and the corner positioning blocks 130 are set one by one, and the corner positioning blocks 130 are installed on the corresponding bottom rods 120. In other embodiments, two or even three corner positioning blocks 130 can also be installed on one bottom rod 120 to simultaneously fix a plurality of wooden frames of different sizes, and those skilled in the art can select the number of corner positioning blocks 130 installed on each bottom rod 120 according to actual needs.

[0045] In this embodiment, the corner positioning block 130 is adjustably connected to the bottom rod 120 .

[0046] Specifically, the bottom rod 120 is provided with a plurality of positioning holes 121, and the positioning holes 121 are through holes. The positioning holes 121 penetrate the bottom rod 120 along the thickness direction of the bottom rod 120, and the plurality of positioning holes 121 are arranged at equal intervals along the length direction of the bottom rod 120. The corner positioning block 130 is fixed with a positioning pin 131, and the positioning pin 131 is plugged into any positioning hole 121. The size of the positioning pin 131 matches the size of the positioning hole 121. After the positioning pin 131 is inserted into any positioning hole 121, it will not become loose. By setting a plurality of positioning holes 121 to cooperate with the positioning pin 131, the position of the corner positioning block 130 relative to the bottom rod 120 can be adjusted, so that it can adapt to wooden frames of different sizes.

[0047] The two ends of the fixing block in the length direction are arranged in a semicircle, and one end of the bottom rod 120 is hinged to the fixing block so that the bottom rod 120 can be adjusted relative to the fixing block. In addition, one end of the bottom rod 120 connected to the fixing block is provided with a rounded corner or a semicircular design so that the two bottom rods 120 will not be hindered when rotating.

[0048] The fixing blocks of the two folding units 100 are respectively set as the second fixing block 112 and the first fixing block 111. When the clamp is unfolded, the two folding units 100 are symmetrically arranged, and the second fixing block 112 and the first fixing block 111 are relatively fixed.

[0049] In this embodiment, the second fixing block 112 and the first fixing block 111 are detachably connected.

[0050] Specifically, the second fixing block 112 is connected to the first fixing block 111 via a connecting assembly. In this embodiment, the second fixing block 112 is detachably connected to the first fixing block 111 via the connecting assembly.

[0051] Specifically, the connection assembly includes a locking shaft and a locking head 230 .

[0052] Specifically, in this embodiment, the locking shaft includes a second connecting rod 220 and a first connecting rod 210. In this embodiment, the first connecting rod 210 and the second connecting rod 220 are two components formed by cutting a complete screw rod into two halves in the middle of the length direction. In other embodiments, the first connecting rod 210 and the second connecting rod 220 can also be set as two separately manufactured components. Those skilled in the art can select the manufacturing method of the first connecting rod 210 and the second connecting rod 220 according to actual needs.

[0053] The first connecting rod 210 and the second connecting rod 220 are hingedly connected. Specifically, in the present embodiment, two connecting plates and two connecting pins are provided between the first connecting rod 210 and the second connecting rod 220. The two connecting pins are respectively inserted into the first connecting rod 210 and the second connecting rod 220. The two ends of the connecting plate are respectively hingedly connected to the two connecting pins, thereby realizing the hinged connection between the first connecting rod 210 and the second connecting rod 220. In other embodiments, the first connecting rod 210 and the second connecting rod 220 may also be directly connected through a rotating shaft so that the first connecting rod 210 and the second connecting rod 220 are hingedly connected. Those skilled in the art may select the hinged structure of the first connecting rod 210 and the second connecting rod 220 according to actual needs.

[0054] One end of the first connecting rod 210 away from the second connecting rod 220 is fixedly connected to a limiting head 240, and the limiting head 240 is integrally formed with the first connecting rod 210. The limiting head 240 is used to limit the relative position between the first connecting rod 210 and the first fixing block 111.

[0055] The first connecting rod 210 passes through the first fixing block 111 , and the limiting head 240 is disposed on a side of the first fixing block 111 away from the second fixing block 112 .

[0056] In other embodiments, the locking shaft may also be configured as a complete screw structure, eliminating the foldable function of the locking shaft, and those skilled in the art may select the specific structure of the locking shaft.

[0057] In other embodiments, the locking shaft can also be configured as a screw structure with three sections hinged in sequence, wherein the middle section has a sufficient length so that the folding screw can be folded or unfolded along with the two folding units 100. Before the two folding units 100 are stacked, stored or unfolded, there is no need to separate one of the folding units from the locking shaft. By configuring in this way, the folding and storage time of the portable board wood processing clamp can be greatly reduced, thereby improving the work efficiency of the staff.

[0058] When the clamp is in the unfolded state, the second connecting rod 220 passes through the second fixed block 112, and the locking head 230 is threadedly connected to the second connecting rod 220. The locking head 230 is pressed against the end of the second fixed block 112 away from the first fixed block 111. At the same time, the limiting head 240 is pressed against the end of the first fixed block 111 away from the second fixed block 112. Through the joint action of the limiting head 240 and the locking head 230, the relative fixation of the second fixed block 112 and the first fixed block 111 is completed.

[0059] Specifically, the first fixing block 111 is provided with a functional slot group, and the functional slot group includes a nut locking slot 142 and a rod receiving slot 141 .

[0060] The rod receiving groove 141 is formed on the end surface of the first fixing block 111 in the length direction, and the rod receiving groove 141 extends along the length direction of the first fixing block 111. Both ends of the rod receiving groove 141 penetrate through the two end surfaces of the first fixing block 111 in the length direction. The rod receiving groove 141 is used to receive the second connecting rod 220.

[0061] The nut retaining groove 142 and the rod receiving groove 141 are arranged on the same side wall of the first fixed block 111. There are two nut retaining grooves 142, which are symmetrically arranged on both sides of the first fixed block 111. The two nut retaining grooves 142 are arranged along the length direction of the first fixed block 111. The nut retaining groove 142 is used to cooperate with the locking head 230 to restrict the second connecting rod 220, so that the second connecting rod 220 will not easily fall out of the rod receiving groove 141 after being folded and stored.

[0062] Specifically, in this embodiment, the number of functional slot groups is set to two, and the two functional slot groups are respectively arranged on both sides of the first fixing block 111 in its width direction. By setting it in this way, the time for workers to distinguish the front and back sides when assembling the clamp can be reduced, thereby effectively improving the assembly efficiency.

[0063] Specifically, the second fixing block 112 and the first fixing block 111 are two components with the same structure. The first fixing block 111 and the second fixing block 112 can be produced using the same mold or the same processing method, which reduces the number of different structural parts and reduces the overall production time of the fixture.

[0064] When the clamp is not in use, the two folding units 100 are separated, the first connecting rod 210 remains connected to the first fixing block 111, so that the first connecting rod 210 is retained in one of the folding units 100, the second connecting rod 220 rotates relative to the first connecting rod 210 to fold the locking shaft, and the rod receiving groove 141 can receive the folded second connecting rod 220. After the second connecting rod 220 is set in the rod receiving groove 141, the probability of the second connecting rod 220 colliding with other objects can be reduced, thereby protecting the second connecting rod 220. And after the locking shaft is folded, the locking shaft is retained in one of the folding units 100, which can effectively avoid the loss of the locking shaft, and also avoid the separation of the locking shaft from the folding unit 100, so as to avoid the trouble of finding the locking shaft to connect the two folding units 100, and facilitate the rapid assembly of the clamp when the clamp is used next time.

[0065] The use process of the clamp is as follows: when the wooden strips need to be fixed, first unfold the two folding units 100, and then place the fixing blocks of the two folding units 100 flush with each other to combine the two folding units 100 into a clamp.

[0066] Then, the positions of the bottom rod 120 and the corner positioning blocks 130 are preliminarily adjusted. After the positions of the bottom rod 120 and the corner positioning blocks 130 are preliminarily adjusted, the wooden strips to be spliced ​​are put in. According to the splicing size of the wooden strips, the positions of the bottom rod 120 and the corner positioning blocks 130 are adjusted again so that the four spliced ​​wooden strips are neatly placed to form a rectangular wooden frame. Subsequently, the fixed blocks of the two folding units 100 are connected through a connecting assembly. Specifically, the first connecting rod 210 and the second connecting rod 220 are respectively passed through the first fixed block 111 and the second fixed block 112, and then the locking head 230 is rotated so that the four corner positioning blocks 130 clamp the four corners of the wooden frame and make the two fixed blocks relatively fixed to prevent the wooden strips spliced ​​on the four sides from loosening during processing.

[0067] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
