Abstract

The utility model discloses a auto-lock box spanner drive arrangement, it includes: the cross section of one end of the driving head is dodecagon, the middle part of the driving head is provided with a driving stop block, and the cross section of the other end of the driving head is quadrilateral; the diameter of the driving block is larger than that of the dodecagon driving head; the four-side drive is provided with a buckle device, and a socket wrench connecting rod and a socket wrench of different specifications are arranged in cooperation with the buckle device. The utility model aims at providing a auto-lock box spanner drive arrangement solves the problem that there is the dynamics inadequately and causes the injury to the periphery of nut easily in current ratchet spanner technique.

Description

Self-locking box spanner drive unit

Technical field:

The present invention relates to a kind of hardware & tools, specifically self-locking box spanner drive unit, especially a kind of handled easily, can automatically reset sleeve drive, its one end 4 driving head becomes 12 horn shapes, and the other end 1 four limit drives box spanner and the box spanner extension bar that can accept different size.

Background technology:

In producing in the market, box socket set torsion used is too little, firmly easily bad, seems not very convenient.

The artificial solution of invention is convenient to use, utilize spring automatic reset mechanism 9 spanner hook will withstand 4 driving head automatic lockings, positive direction twisting can make 9 spanner hooks and 11 spanner teeth that 4 driving heads are locked, twisting in the other direction can make 9 spanner hooks and 11 spanner teeth loosen from 4 driving heads unblocks automatically, uses convenient.

Utility model content:

For the deficiencies in the prior art, the utility model provides a kind of self-locking box spanner drive unit, solves existing ratchet spanner technology and there is dynamics problem that is inadequate and that easily damage the periphery of nut.

Its technical solution is: a kind of self-locking box spanner drive unit, and it includes: one end cross section is dodecagonal driving head (4), and centre is provided with and drives block (3), and other end cross section is that four limits of quadrangle drive (1); And drive block (3) larger than the diameter of dodecagonal driving head (4); Four limits drive (1) to be provided with bayonet unit (2), are equipped with box spanner connecting rod (13) and the box spanner (14) of different size with bayonet unit (2).

Beneficial effect:

Self-locking box spanner drive unit, be provided with the anti-skidding driving head of bihexagonal, resetting-mechanism, can make just can automatic unlocking to twisting in the other direction, positive direction twisting can make spanner hook and the hand tooth that shakes does one's utmost to lock driving head, dynamics is very big, and activity freely, solves the dynamics of the ratchet spanner use that spanner in prior art improves, also the flexibility of ratchet spanner can be reached, easy to use.

Solve existing ratchet spanner technology and there is dynamics problem that is inadequate and that easily the periphery of nut is damaged.

Accompanying drawing illustrates:

Fig. 1 is driving schematic diagram of the present invention;

Fig. 2 is self-locking box spanner drive unit side schematic view of the present invention;

Fig. 3 is that driving head of the present invention connects and establishes switching schematic diagram;

Description of reference numerals:

1 four limit drivings in figure, 2 bayonet units, 3 drive block, 4 driving heads, 5 spanner glue handles, 6 spring inner sleeves, 7 steel balls, 9 spanner hooks, 10 spanner cheicers, 11 spanner teeth, 12 rivets, 13 box spanner extension bars, 14 box spanners.

Detailed description of the invention:

Relevant the technology used in the present invention, means and effect thereof, hereby lift a preferred embodiment and coordinate figure style to state as rear, this is only for instructions, the restriction not by this kind of structure in patent application.

With reference to the driving then face schematic diagram of Fig. 2, self-locking box spanner drive unit of the present invention, driving head 4 is dodecagon shape, rivet 12 through the activity of spanner hook 9 energy freely, utilize the steel ball 7 of spring automatic reset mechanism to withstand spanner hook 9 on driving head 4, opposite direction twisting automatic unlocking loosens maintenance spanner hook 9 spanner tooth 11 and is enclosed within above driving head 4, difficult drop-off, positive direction twisting just makes spanner hook 9 spanner tooth 11 firmly pin driving head 4 simultaneously, and strength is very big.

Described driving block 3 is larger than the diameter of driving head 4, spanner hook 9 can be blocked when both forward and reverse directions twisting not easily to walk about, four limits drive 1 to be provided with bayonet unit 2, bayonet unit 2 can coordinate the box spanner extension bar 13 of different size and box spanner 14, four limit driving 1 can accept box spanner extension bar 13 and the box spanner 14 of different size.

Claims

1. a self-locking box spanner drive unit, is characterized in that: it includes: one end cross section is dodecagonal driving head (4), and centre is provided with and drives block (3), and other end cross section is that four limits of quadrangle drive (1); And drive block (3) larger than the diameter of dodecagonal driving head (4); Four limits drive (1) to be provided with bayonet unit (2), are equipped with box spanner connecting rod (13) and the box spanner (14) of different size with bayonet unit (2).
