昭４ー６７１２９号）。2. Description of the Related Art A screw tightening machine using a connecting screw in which a plurality of screws are connected to a connecting band made of a synthetic resin at regular intervals is easy to bend because the connecting band has low rigidity. Therefore, a mechanism has been proposed in which a guide member for accommodating the connecting screw is attached to the screw tightening machine main body, and the guide screw is supplied from the guide passage of the guide member to the driving portion of the screw tightening machine (Japanese Utility Model Application No. 4-67129). issue).

る欠点があった。However, the guide passage is formed in parallel with the screw driving direction, and the connecting screw is formed so as to be freely movable into the guide passage. The connecting screw easily slips out of the guide passage and slides down, which hinders the screw tightening operation and causes a defective feeding of the connecting screw.

る。In order to achieve the above-mentioned object, in order to achieve the above object, a mechanism for preventing a connecting screw from slipping down in a screw tightening machine according to the present invention is a guide member having a guide passage for guiding and supplying a connecting screw to a screw driving portion. In the screwing machine attached to the main body of the screwing machine, the guide passage is provided with a sliding member rotatably mounted on a pair of stoppers opposed to each other with the shaft of the connecting screw interposed therebetween. The pair of stoppers are slidably slidable along the direction and arranged in the opposite direction to the supply direction of the connecting screw, and the ends of the pair of stoppers are engaged with the screw shaft in the guide passage. Overhang position,
The guide passage is rotatable between a retracted position allowing the passage of the screw shaft and the spring, and is always biased by a spring so as to protrude into the guide passage. When the sliding member slides in the screw supply direction, a stop wall is formed which engages with the end faces of the both stoppers to prevent the stoppers from rotating to the retracted position.

に回動させて連結ネジを引き出すことができる。In a normal screw tightening operation in which the screw tightening machine body is turned sideways or upward, the sliding member is urged in a direction opposite to the supply direction of the connecting screw, and at this time, the pair of stoppers are at the overhanging position. When the screw is supplied to the driving portion by the feed mechanism, the end of the stopper engages the screw shaft of each screw, but the feed force of the connecting screw allows the screw shaft to pass through against the bias of the spring. Rotate to the retracted position. When the connecting screw is pulled out from the rear end of the guide member in the middle of the work, the stopper in the extended position can be similarly turned to the retracted position to pull out the connecting screw.

このため、ネジ軸はストッパの端部に係合し、それ以上
下方に（前方に）移動することはできない。On the other hand, when the screwdriver body is turned downward, the sliding member slides in the connecting screw supply direction due to gravity, and the end face of the stopper engages with the stop wall at the sliding end.
Since the stopper is in the extended position when sliding, the stopper is held in the extended position when engaged with the stop wall.
For this reason, the screw shaft engages the end of the stopper and cannot move further downward (forward).

First, the connecting screw 1 is loaded from the rear end of the guide member 5, the front end of the connecting screw 1 is set in the driving portion 2, and then the screw is tightened. I do. During normal screw tightening performed with the screw tightener body 4 turned sideways or upward, the sliding member 8 is held at a rear position by a tension spring 10 and a steel ball 11. In this case, a pair of stoppers 14
6A and 6B, when the connecting screw 1 is supplied to the driving portion 2 by the feed mechanism, the end 14a of the stopper 14 is connected to the screw shaft b1 of each screw as shown in FIGS. However, the connecting screw 1 rotates to a retracted position where the screw shaft b1 can pass against the spring force of the torsion coil spring (17) by the feed force of the connecting screw 1.

引き出すことができる。When it is necessary to replace the connection screw 1 with another connection screw 1 before the connection screw 1 is completely consumed, the connection screw 1 loaded in the guide member 5 is removed during the operation. It needs to be pulled out from the rear end. In this case, as shown in FIGS. 7 (a) and 7 (b), when the pulling force of the connecting screw 1 is made larger than the spring force of the torsion coil spring (17), the stopper 14 at the projecting position is moved to the screw shaft b1.
The connecting screw 1 can be pulled out by rotating to a retracted position that allows passage of the connecting screw 1.

め作業も行なうことができる。On the other hand, when the operator turns the screw tightening machine body 4 downward, the steel ball 11 moves into the receiving groove 13, so that the sliding member 8 is connected to the tension spring 1.
It slides downward (in the connection screw supply direction) by gravity against the spring force of 0. Then, as shown in FIG. 8, the end face 14 b of the stopper 14 engages with the stop wall 18 at the sliding end. Since the stopper 14 is in the extended position when sliding, the stopper 14 is held in the extended position when engaged with the stop wall 18. For this reason, the screw shaft b1 engages with the end 14a of the stopper 14, and moves downward (forward).
You cannot move. Therefore, the sliding of the connecting screw 1 is effectively prevented. Therefore, a downward screw tightening operation can be performed.
