Abstract
The utility model relates to a special tool for conveniently installing and disassembling bolts in narrow space, which is provided with a fixed bayonet with a baffle plate, wherein the bayonet clamps nuts which can not be clamped by a spanner, and the fixed bayonet can not fall off from a nut through an elastic compressing device. The utility model has the advantages of easy processing and low cost.
Description
Affiliated technical field
The utility model relates to a kind of specific purpose tool, particularly is applicable to the bolt loading and unloading of small space.
Background technology
Existing bolt loading and unloading tool, at loading and unloading small space bolt, in the time of can't blocking other end nut with instruments such as wrench, often can't load and unload, at this moment, adopt and to load and unload again after the basis is destroyed or other object removes on every side, fill again after waiting completed loading loading and unloading around the bolt, so very bothersome, wasted lot of materials simultaneously.
Summary of the invention
In order to address this problem, the utility model provides a kind of and can fix the inner end nut at small space, when bolt being loaded and unloaded in the outer end, and the specific purpose tool that makes the inner end nut not rotate and move.
The object of the present invention is achieved like this: a kind of specific purpose tool, with a fixedly bayonet socket that has a nut plate washer, nut is blocked, stressed rod on one extension arm being arranged behind the bayonet socket and can being pressed in flange or equipment gabarit is connected, effect by stressed handful and flange or equipment gabarit makes nut block unlikely rotation, for fear of bayonet socket being dropped because of this instrument gravity, connecting a cover at stressed stick end can carry out length adjustment and have the hold down gag of elastic force by screw thread, this device handle roof pressure is on the flange or equipment gabarit of the nut other end that is stuck, thereby make fixedly bayonet socket or nut plate washer to nut or flange and equipment gabarit effect one normal pressure, make that bayonet socket is unlikely to drop.
The utility model overlaps very simple tools because only need to increase by one, one small space that can supply staff to enter is being arranged, make the loading and unloading bolt be easy to, because this instrument is when the different big stove bolt of loading and unloading, only need to change the different fixing bayonet socket, thereby use easily, there is not the complicated processing part simultaneously, cheap.
Description of drawings

Figure the-2nd, a left side of the present utility model (cuing open) view.
The specific embodiment
As shown in Figure 1, this utility model is provided with fixedly a bayonet socket (1) and a nut plate washer (2) that can be by screw rod, blocks and is fixingly adorned but nut, makes its unlikely rotation and moves.Fixedly bayonet socket (1) and moment of torsion reach stressed rod (4) as shown in Figure 2 by bayonet arm (3), act on flange or equipment gabarit by stressed rod (4) and be absorbed, for fear of because of but axial float during pine of gravity and bolt, bayonet socket (1) drops from nut and make fixedly, in the end of stressed rod (4), having one can be according to flange or equipment gabarit thickness, hold down of elasticity by threaded adjusting length, this device passes through threaded adjusting length by spring pressure shell (5) in stressed rod (4), because handle (11) is that roof pressure is on the flange or equipment gabarit of the nut other end that is stuck, when spring pressure shell (5) enters stressed rod (4), by pad (9), the effect of clamp nut (10), make handle (11), spring tension bar (6), spring base (8) is an integral body, and the compression spring (8) thus produce a resilient force on handle (11), because reaction force, make on the fixedly bayonet socket (1) or nut plate washer (2) of the other end, be subjected to a normal pressure, make fixedly bayonet socket (1), nut plate washer (2), nut is pressed on flange or the equipment gabarit, thereby makes fixedly unlikely the dropping of bayonet socket (1).
Claims (2)
1, a kind of specific purpose tool is provided with fixedly a bayonet socket and a nut plate washer, it is characterized in that: an extension arm and stressed rod are arranged at the bayonet socket rear portion.
2, specific purpose tool according to claim 1 is characterized in that: stressed stick end has a length-adjustable hold down of elasticity.
