Abstract
The utility model relaes to a runner type double offset ring spanner which belongs to a tool, particularly a spanner which is composed of a runner and a handle, wherein the circumferential surface of the outer ring of the runner is provided with a ratchet, the center of the runner is a quincunx-shaped spanning hole, and a circle of groove is arranged between the ratchet of the runner nad the quincunx-shaped spanning hole; correspondingly, the top of the handle is provided with a dummy club which is clamped in the groove of the ruuner, the runner and the handle can opposite rotate, and meanwhile, a brake shoe is arranged in the handle and is abutted on the ratchet of the runner through a spring. The spanner of the utility model can lock or loosen an object without departing from a nut to realize continuous spanning, and has compact structure without a sleeve barrel; due to the ultra-thin design, the utility model is especially suitable for narrow space to use, can be extended into various machines, and is particularly suitable for places that people only use hands to feel the nut.
Description
One, technical field
The utility model belongs to the instrument class, is specifically related to a kind of spanner.
Two, background technology
Existing double offset ring spanner can not be pulled continuously, thereby wastes time and energy; Though the spanner that has can be pulled continuously, because a sleeve is arranged, volume ratio is bigger, and the scope of application is restricted, and can't be suitable for the bigger screw of some length.
Three, technology contents
The purpose of this utility model provides a kind of rotary-type double offset ring spanner, and it both can be pulled continuously, and compact conformation, volume are little, is applicable to the screw-nut of all lengths.
Technical solutions of the utility model are as follows: a kind of rotary-type double offset ring spanner, comprise handle and the quincunx hole of pulling, it is characterized in that forming by runner and handle two parts, runner outer ring circumferential surface is provided with ratchet, the runner center is the quincunx hole of pulling, and is provided with a circle groove between the hole at runner ratchet and quincunx pulling; Correspondingly, handle top is provided with boss one, and this boss is positioned in the runner groove, can relatively rotate between runner and the handle, simultaneously, is provided with a brake(-holder) block in the handle, and this brake(-holder) block is against on the runner ratchet by spring.
Above-mentioned rotary-type double offset ring spanner can be pulled continuously, move back and forth about handle 25 degree, just can make runner 360 degree rotations, spanner need not leave nut just can lock or unclamp object, can not twist 2 centimeters long screws under the 360 degree rotating conditions at handle, more fast again than common wrench.The utility model does not have sleeve, can directly be enclosed within on the nut, structure is very compact, required activity space is very little, its ultrathin type design makes it to be highly suitable for narrow space and uses, can reach various machines the inside to spanner and go locking or unclamp nut, can only go to feel to use this rotary-type double offset ring spanner the most suitable in the narrow space that nut exists with hand.

Fig. 2 is the side view of the rotary-type double offset ring spanner of the utility model.
Fig. 3 is a handle head inside structure schematic diagram.
Five, the specific embodiment
In the illustrated embodiment, rotary-type double offset ring spanner comprises handle and the quincunx hole of pulling, it is characterized in that forming by runner (1) and handle (2) two parts, runner outer ring circumferential surface is provided with ratchet (3), the runner center is the quincunx hole (4) of pulling, and respectively is provided with a circle groove (5) at runner ratchet and the quincunx tow sides of pulling between the hole; Correspondingly, handle top is provided with one boss (6), and as shown in Figure 3, the handle head is formed by two, and in the middle of runner was clipped in, as shown in Figure 2, the boss on the handle was positioned in the runner groove, can relatively rotate between runner and the handle; Simultaneously, be provided with a brake(-holder) block (7) in the handle, be fixed on the handle by pin (9), this brake(-holder) block is against on the runner ratchet by spring (8).During work, on nut, swing handle utilizes the gradient of ratchet that brake(-holder) block is depressed to the right with rotaring wheeling sleeve, according to handle swinging distance size, makes brake(-holder) block move a tooth or multiple tooth backward; Because spring to the ratchet depths, when swing handle left, utilizes brake(-holder) block top brake(-holder) block block runner and drives nut, nut is turned clockwise tighten.
