Abstract

The invention discloses a combined wrench capable of quickly tightening a nut on a bolt, which is characterized in that the combined wrench comprises a hollow outer sleeve (1), a hollow inner sleeve (4) and a crank (7), wherein the hollow outer sleeve (1) is longitudinally provided with a groove (3), the top end of the outer sleeve (1) is provided with a bayonet (2) for clamping the head of the bolt, and the bottom end of the outer sleeve is provided with an internally threaded opening; the hollow inner sleeve (4) is movably sheathed in the outer sleeve (1), the top end of the inner sleeve (4) is provided with a movable bayonet (5) for clamping the nut, the bottom end of the inner sleeve (4) is connected with a screw (6), and threads of the screw (6) are matched with threads of the internally threaded opening on the bottom end of the outer sleeve; and the crank (7) is provided with a handle, and the crank is connected with the screw. The nut can be quickly tightened on the bolt by the combined wrench, and operation tasks can be finished without using other wrenches to fix the bolt. The combined wrench has the advantages of simple structure, low production cost and high practicability. Different sizes of wrenches can be produced according to requirements.

Description

The combination wrench of top nut fast tights a bolt
Technical field
The present invention relates to the nut screwing clamping instrument, specifically a kind of combination wrench of the top nut that tights a bolt fast.
Background technology
Existing spanner, no matter be solid wrench or adjustable wrench, when stubborn bolt top nut, need a spanner fix bolt head, remove nutting with another spanner then, people comparison difficulty that operates, same reason, if when tightening a certain parts of clamping mutually by two nuts on the screw rod, also be have a spanner to fix one of them nut earlier, could come fastening nut with another spanner.
Summary of the invention
The present invention is in order to solve the weak point that prior art exists, a kind of combination wrench of the top nut that tights a bolt fast to be provided, and simple, convenient and practical property is strong.
Technical solution problem of the present invention adopts following scheme:
Quick fastening nut combination wrench, its design feature is: comprise
One vertically has the hollow sleeve tube of sipes, and described outer sleeve top is provided with the bayonet socket that blocks nut or bolt head, and the outer sleeve bottom is an inner thread mouth;
One activity is placed in the hollow inner sleeve in the outer sleeve, and the top of described inner sleeve is provided with the bayonet socket alive that blocks nut, and the bottom connects one and has the external screw thread bolt, the screw thread of described bolt and outer sleeve bottom inner thread mouth threads engaged;
The crank of one band handle, described crank is connected with bolt.
Design feature of the present invention also is: described screw rod removably connects with inner sleeve, crank respectively.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention's top nut that can tight a bolt fast can the complete operation task and need not fix bolt by other spanners, and the present invention is equally applicable to two nuts (tightening a certain parts of clamping mutually by two nuts) on the screw rod.
2, the present invention is simple in structure, and production cost is low, and applicability is strong, can just produce the spanner of different size as required.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is user mode figure of the present invention.
Fig. 3 is a parts dispersed structure schematic diagram of the present invention.
Number in the figure: 1 outer sleeve, 2 bayonet sockets, 3 notches, 4 inner sleeves, 5 bayonet sockets alive, 6 screw rods, 7 cranks.
The present invention will be further described by embodiment below in conjunction with accompanying drawing.
The specific embodiment
Referring to Fig. 1 to Fig. 3 combination wrench, comprise that one vertically has the hollow sleeve tube 1 of notch 3, outer sleeve 1 top is provided with the bayonet socket 2 that blocks bolt head, and the outer sleeve bottom is an inner thread mouth; One activity is placed in the hollow inner sleeve 4 in the outer sleeve 1, and the top of inner sleeve 4 is provided with the bayonet socket alive 5 that blocks nut, and the bottom connects a screw rod 6, the screw thread of screw rod 6 and outer sleeve bottom inner thread mouth threads engaged; The crank 7 of one band handle, crank is connected with screw rod.
Screw rod 6 in the present embodiment promptly can be to removably connect integral type is connected with inner sleeve 4, crank respectively.
Using method: at first spanner outer sleeve 1 is embedded bolt in the outer sleeve by notch 3 and also fix bolt head with the bayonet socket 2 on outer sleeve 1 top, then the bayonet socket alive 5 of inner sleeve 4 is blocked the nut on the bolt, hold tight outer sleeve for one, another is hand to shake 7, crank drives screw rod 6 to be changeed in the outer sleeve inward turning, the screw rod rotation drives inner sleeve 4 and rotates, because of inner sleeve 4 top bayonet sockets block nut, therefore can tighten fast or loose nut, tightening or during loose nut, bolt also is enclosed in the inner sleeve of hollow.

Claims (2)

1. tight a bolt the fast combination wrench of top nut is characterized in that: comprise
One vertically has the hollow sleeve tube (1) of notch (3), and described outer sleeve (1) top is provided with the bayonet socket (2) that blocks bolt head, and the outer sleeve bottom is an inner thread mouth;
One activity is placed in the hollow inner sleeve (4) in the outer sleeve (1), and the top of described inner sleeve (4) is provided with the bayonet socket alive (5) that blocks nut, and the bottom connects a screw rod (6), the screw thread of described screw rod (6) and outer sleeve bottom inner thread mouth threads engaged;
