Detailed Description

The utility model discloses a carpenter's anchor clamps structure, its activity arm lock are established and are held room space equipment and have a plurality of block and hold the piece, and the screw sleeve supports back block and hold the piece with elastic element top, and the screw thread beyond the screw sleeve is worn out the activity arm lock and is fixed with revolving the screw lock, makes the activity arm lock clip wooden work piece revolve again and can fix wooden work piece screwing, and its component is simple easily to be assembled.

Referring to fig. 1 to 4, the present invention provides a carpentry clamp structure, which includes a fixed clamping arm 1 having a first clamping surface 11;

one end of the shaft lever 2 is transversely fixed below the fixed clamping arm 1 and vertically corresponds to the first clamping surface 11;

a movable clamping arm 3, the movable clamping arm 3 having a second clamping surface 31 corresponding to the first clamping surface 11, a containing space 32 below the movable clamping arm 3, and a rear through hole 33 communicating with the containing space 32 behind the movable clamping arm;

an annular inner bushing 4, a convex ring 41 reversely buckled inside the containing chamber space 32 is formed outside one end of the annular inner bushing 4, and the other end of the annular inner bushing 4 penetrates through the rear through hole 33 to present a pattern of exposed movable clamping arms 3;

a handle 5, the handle 5 is a tubular hollow type, the inner side of one end of the handle 5 is sleeved and fixed on the exposed section of the annular inner bushing 4, and the inner diameter of the handle 5 is formed with an inner thread section 51;

an inner sleeve member 6, the inner sleeve member 6 is hollow and is used for the shaft lever 2 to wear, the inner sleeve member 6 has a first portion 61 arranged in the containing space 32, and a second portion 62 passing through the annular inner bush 4 and the handle 5, the inner sleeve member 6 is provided with at least one locking plate 63 sleeved on the shaft lever 2 at the inner side of the first portion 61, and a spring 64 which is elastically propped between the inner sleeve member 6 and the locking plate 63, so that the locking plate 63 is engaged with the shaft lever 2 by normal force deflection, the outer side of the second portion 62 of the inner sleeve member 6 is provided with an outer thread section 65 screwed with the inner thread 51 section;

the movable clamping arm 3 is provided with a front cover 34 covering the front open end of the accommodating space 32, the front cover 34 is provided with a front through hole 341 for the shaft rod 2 to pass through, and the inner surface of the front cover 34 is provided with an abutting projection 342 for guiding after the clamping plate 63 is pushed and abutted;

thus, when the inner sleeve 6 is located at the foremost end of the accommodating space 32, the detent plate 63 is contacted by the abutting projection 342 to assume a guiding state, and at this time, the detent plate 63 is disengaged from the shaft rod 2, and the grip 5 is pushed to rapidly control the clamping distance between the fixed clamping arm 1 and the movable clamping arm 3 (as shown in fig. 3); when the first clamping surface 11 and the second clamping surface 31 clamp the workpiece, the handle 5 is continuously rotated to drive the inner member 6 to slightly move back, and when the clamping plate 63 loses contact with the abutting projection 342, the clamping plate is deflected under the influence of the spring 64 to be in a meshing state with the shaft rod 2 (as shown in fig. 4), at this time, when the handle 5 is continuously rotated, the handle 5 is screwed relative to the inner member 6 to push the movable clamping arm 3, so that the clamping effect of the movable clamping arm 3 and the fixed clamping arm 1 is more stable.

Further, a ring-shaped step 52 is formed inside the handle 5, a limiting ring 66 is locked on the end surface of the second portion 62 of the inner sleeve 6 and is positioned with the ring-shaped step 52, and the limiting ring 66 has a through hole 661 for the shaft rod 2 to pass through; therefore, the limiting ring 66 serves as a back-off surface at one end of the inner sleeve 6, so that the maximum displacement distance of the inner sleeve 6 can be effectively limited.

Further, the handle 5 is locked with a screw 53 locked with the annular inner bushing 4; thus, the screw 53 serves as a fixing means for connecting the grip 5 and the annular inner liner 4.

Furthermore, the carpenter's clamp of the present invention comprises a coil spring 7 screwed between the internal thread section 51 and the external thread section 65; thus, the helical spring 7 is used as a driving medium between the internal thread section 51 and the external thread section 65, so that the torque bearing degree of the two during bearing driving can be effectively improved.

In view of the above, the present invention provides a carpentry clamping structure, which has the features of simple and easy assembly, and in addition, when the handle rotates, the movable clamping arms can be pushed by the carpentry clamping structure or pulled by the annular inner sleeve, so that the handle and the movable clamping arms can always keep close to each other during the linkage process, thereby avoiding the situation that the outer thread section on the inner sleeve is exposed during the rotation of the handle, and wood chippings or dust falls into the inner sleeve, which causes difficulty in the rotation in the future.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
