[ detailed description ] embodiments

The present invention will be further described with reference to the accompanying drawings and embodiments.

Referring to fig. 1-6, an embodiment of the present invention provides a tapping clamp.

This tapping anchor clamps include: the tapping tool comprises a tapping handle 10, a tapping extension bar 20 connected with the tapping handle 10, an elastic collet 40 for clamping the tapping tool, and a locking member 30 for locking the elastic collet 40. The bottom of the tapping extension bar 20 is provided with a cavity 21 matched with the elastic collet 40, at least part of the elastic collet 40 is arranged in the cavity 21, and the locking member 30 is of a hollow structure. The locking member 30 is sleeved on the elastic collet 40 and detachably arranged on the tapping extension bar 20 for locking the elastic collet 40.

The utility model discloses a tapping anchor clamps utilize elasticity collet chuck 40 to press from both sides after pressing from both sides tight tapping instrument, utilize retaining member 30 cover to locate tapping anchor clamps, locking on tapping extension bar 20 behind the elasticity collet chuck 40 to this can be firm fixed with the tapping instrument, this tapping instrument's mounting means is simple, and the user of being convenient for changes the tapping instrument, prevent that the tapping instrument from droing after manual tapping or tapping completion, with this can solve the problem that tapping drove easily and tapping locking complex operation is comparatively loaded down with trivial details in the current manual tapping extension instrument.

Specifically, referring to fig. 3 to 5, the elastic collet 40 has first and second clamping portions 41 and 44 at two ends thereof, respectively, and the tapping tool can be clamped by the first and second clamping portions 41 and 44, so that the tapping tool can be clamped by the two ends of the elastic collet 40 without installing the tapping tool at one end thereof, which is more convenient for users.

The first clamping portion 41 and the second clamping portion 44 are both composed of at least two clamping plates 43 and a gap 42 for spacing two adjacent clamping plates 43, so that the first clamping portion 41 and the second clamping portion 44 with elasticity are formed, tapping tools with different sizes can be adapted, and the applicability is improved.

The diameter of the first clamping portion 41 gradually decreases in a direction away from the second clamping portion 44, and the diameter of the second clamping portion 44 gradually decreases in a direction away from the first clamping portion 41. The inside diameter of the locker 30 is gradually reduced away from the tapping handle 10 to form the constricted opening 32, i.e., the constricted opening 32, the first grip 41 and the second grip 44 are tapered. Therefore, when the first clamping portion 41 or the second clamping portion 44 clamps the tapping clamp, the locking member 30 can press the first clamping portion 41 or the second clamping portion 44 by using the reduced opening 32, so that the first clamping portion 41 or the second clamping portion 44 clamps the tapping tool, and the clamping plate 43 is matched with the tapping tool, so that the tapping tool cannot drive the elastic collet 40 to rotate together during tapping, and the tapping effect is prevented from being influenced.

In an embodiment, the number of the clamping plates 43 is preferably four, which prevents the width of the clamping plates 43 from affecting the elasticity too much, and the number of the clamping plates 43 may be two, three, or other numbers, which are not limited herein.

In one embodiment, the gap 42 of the first clamping portion 41 and the gap 42 of the second clamping portion 44 are disposed in a staggered manner, as shown in fig. 3, so as to prevent the gap 42 of the first clamping portion 41 and the gap 42 of the second clamping portion 44 from being on the same line to separate the elastic collet 40, which may affect the use.

In one embodiment, the threaded extension bar 20 is provided at the bottom thereof with a first thread 22, and the locking member 30 is provided with a second thread 31 engaged with the first thread 22. The locking member 30 can be locked to the threaded extension bar 20 by the second thread 31 cooperating with the first thread 22.

In one embodiment, at least one flat surface (not shown) is formed on the outer side wall of the locker 30 to facilitate the user's tightening of the locker 30 to the tapping rod 20, thereby preventing slipping.

In an embodiment, tapping handle 10 sets up with tapping extension bar 20 is perpendicular, and the rotatory tapping handle 10 of the user of being convenient for and linkage tapping extension bar 20 rotate and drive the tapping instrument tapping, convenience of customers operation. Specifically, the tapping handle 10 and the tapping extension bar 20 are T-shaped, so that the tapping handle can be conveniently operated by two hands of a user.

In one embodiment, the tapping handle 10 is provided with knurling (not shown) for anti-slip purposes, to prevent slippage when the tapping is manually operated.

In one embodiment, the tapping extension bar 20 is provided with an anti-slip groove (not shown) on the outer side wall thereof for anti-slip. Specifically, the anti-skidding groove is the bar form, and is unanimous on the length direction with tapping extension bar 20, utilizes the anti-skidding groove can prevent that tapping extension bar 20 from skidding, is convenient for screw up retaining member 30 on tapping extension bar 20.

The above embodiments of the present invention are only described, and it should be noted that, for those skilled in the art, modifications can be made without departing from the inventive concept, but these all fall into the protection scope of the present invention.
