Abstract
The utility model relates to a monkey wrench, which comprises a moveable bottom board (1), a movable block (2) and a worm wheel (3). The monkey wrench is characterized in that the springs (7), (8) are arranged below a worm-wheel shaft (4), and the monkey wrench makes the screw teeth on the movable block (2) dissociated from the worm wheel (3); the movable block slides in a sliding slot at the bottom board smoothly. The utility model solves the problem that the adjusting speed moved to the spanner opening is slow in present adjustable wrench.
Description
The utility model is a kind of monkey wrench.
Existing monkey wrench is made of handle base plate (1), movable block (2) and worm gear (3), fastening and when unclamping the nut of various different sizes, the turn worm gear is adjusted the size of wrench opening repeatedly, speed is slow, and when repairing machinery, both hands have been stained with greasy dirt, adjust the spanner worm gear, finger and worm gear skid mutually, use very inconvenience.
The purpose of this utility model is to provide a kind of monkey wrench, on the basis that does not change existing monkey wrench external form, can make things convenient for the size of promptly adjusting the monkey wrench opening.
The utility model is achieved in that below worm-wheel shaft (4), when loading onto spring (7) (8) use, worm gear is pulled down, and the screw thread on the movable block (2) just separates with worm gear, just can slide freely in slideway, then according to the size of nut, sliding shoe is put into the appropriate location, unclamps worm gear, worm gear resets by the strength of spring, worm gear once tightly again, just can nutting.
Because the utility model increases the worm gear separator, mobile wrench opening size is very convenient, rapid, also because the utility model need not to change the external form of existing monkey wrench, so make also very convenient.
The contrast accompanying drawing is described in detail the utility model below.
Figure one is the cutaway view of a specific embodiment of the utility model
Figure two is schematic diagrames under worm gear is pulled in the utility model.
On figure, monkey wrench is by handle base plate (1), movable block (2), worm gear (3) critical piece constitutes, spring (7), (8) and screw (5), (6) increase on the basis of existing technology, its effect is the arrangement of clutch that constitutes worm gear (3) and movable block (2), manufacture method is very simple, earlier the worm-wheel shaft of existing monkey wrench (4) is cut down one section that the length of one section and screw (6) is similar to, and below worm-wheel shaft (4), hole, its space can allow worm-wheel shaft (4) slide freely up and down, and the installing hole of spring (8) is down to bore to form in handle base plate (1) slideway.The installing hole of spring (7) is up to bore from the position of screw (5) to form.The effect of screw (6) is to block worm-wheel shaft (4) to be unlikely and to skid off in the hole, and the effect of screw (5) is top spring (7).From figure two as can be seen, when worm gear (3) is pulled following time, worm-wheel shaft (4) also and then moves down, compression spring (7) (8), at this moment, the screw thread on the sliding shoe (2) separates with worm gear (3), movable block (2) can be slided in slideway freely, when unclamping worm gear (3), the screw thread interlock on worm gear (3) and the movable block (2) just can have been adjusted the degree of tightness of wrench opening.
Claims (1)
- A kind of monkey wrench, it comprises that handle base plate (1), movable block (2) and worm gear (3) is characterized in that being equipped with the arrangement of clutch that spring (7) (8) is constituted below worm-wheel shaft (4).
