Abstract
The utility model provides a device for tightening a screw, belonging to the hardware tool technical field, comprising a main body and a sleeve connected with the main body, wherein a clamp head for clamping a T-shaped screw is fixedly connected with the sleeve. The advantages of the device are that: convenient operation, beautiful appearance, directly clamping the T-shaped screw to tighten the screw using the clamp head, to-and-fro tightening using the feature of the ratchet, convenient operation and use, quick tightening speed and safe and reliable performance.
Description
Technical field
The utility model belongs to the hardware ﹠ tools technical field, relates to a kind of device that is used for tensioning threaded rods.
Background technology
Hand-operated tools all plays the effect that promotes productivity in each society, because the invention and the application of screw, nut and bolt make ratchet spanner become instrument very important in the mechanical hand-operated tools field.All need installation to tighten T shape screw rod on the existing plating line, general three plating lines have 150 to fly rake every day, fly on average to need 8 T shape screw rods of installation on the rake at each, but can not tighten by common ratchet spanner again when tightening T shape screw rod.The existing device that tightens T shape screw rod is for the curved shape of steel wire, and plug blocks screw rod and tightens T shape screw rod in iron pipe, and the shortcoming of Cun Zaiing is like this: 1, not tight on the screw rod, cause conducting electricity bad easily, and product turns to be yellow; 2, see in appearance, not attractive in appearance, inconvenient in the operation, inefficiency.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, and provides a kind of simple and reasonable, and is easy to operate, tightens the high a kind of device that is used for tensioning threaded rods of efficient.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of device that is used for tensioning threaded rods, and comprise body and be connected the body upper bush, it is characterized in that: be fixed with the chuck that is used to clamp T shape screw rod on the described sleeve.
The place of the utility model greatest improvement is on the basis of original ratchet spanner, the chuck that can clamp T shape screw rod that has been connected in the sleeve position, and operation is gone up and just can be utilized the characteristics of ratchet back and forth to tighten like this, and speed is fast.
The measure of taking for the optimization such scheme specifically comprises:
At above-mentioned a kind of device that is used for tensioning threaded rods, offer the suitable clip slot of T shape screw rod on the described chuck, on the madial wall of clip slot, be shaped on latch.Here improve chuck and T shape screw rod stability in contact by latch, prevented from when tightening T shape screw rod, to skid, thereby tightened T shape screw rod apace.
At above-mentioned a kind of device that is used for tensioning threaded rods, described chuck is sleeved on the sleeve, and chuck is fixed together by welding and sleeve.Make whole device form one, better appearance on the profile like this.
Compared with prior art, advantage of the present utility model is easy to operate, and good looking appearance is directly clamped T shape screw rod by chuck and tightened, and can utilize the characteristics of ratchet back and forth to tighten in the operation, and easy for operation, it is fast to tighten speed, and performance is safe and reliable.
Description of drawings
Fig. 1 is the overall structure schematic diagram that originally is used for the device of tensioning threaded rods;
Fig. 2 is the chuck overall structure schematic diagram among Fig. 1;
Fig. 3 is the plan structure schematic diagram of Fig. 2.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Among the figure, body 1; Sleeve 2; Chuck 3; Clip slot 31; Latch 32.
As Fig. 1, Fig. 2 and shown in Figure 3, originally the device that is used for tensioning threaded rods, comprise body 1 and be connected body 1 upper bush 2, here body 1 and be connected body 1 upper bush 2 and be the basic structure of common ratchet spanner, the utility model tightens T shape screw rod for convenience, on the basis of original ratchet spanner, improve, be fixed with the chuck 3 that is used to clamp T shape screw rod on the described sleeve 2, chuck 3 processing of after processing, turning black, chuck 3 described here is sleeved on the sleeve 2, chuck 3 is fixed together by welding and sleeve 2, and both are polished smooth, thereby guarantees good looking appearance.
Offer the suitable clip slot 31 of T shape screw rod on the chuck 3, on the madial wall of clip slot 31, be shaped on latch 32.Here improved chuck 3 and T shape screw rod stability in contact by latch 32, prevented from when tightening T shape screw rod, to skid, thereby tighten T shape screw rod apace.
As long as chuck 3 is clamped T shape screw rod, utilize the characteristics of ratchet back and forth to tighten and get final product during use, convenient to operation.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the defined scope of spirit of the present utility model.
